According to sources close to the situation, AOL has been busy selecting the board for the company, which is still set to spin itself off by year’s end–even as it slows down a decision on a new search deal with either current partner Google or a more emboldened Microsoft.

AOL is using Spencer Stuart in the search for directors, led by well-known headhunter Jim Citrin, sources said, and the company has already settled on several outside candidates.

The final board is likely to have about 10 members, and up to a dozen.

At least one of those seats will go to CEO Tim Armstrong, with one or two more claimed by its current corporate owner, Time Warner (TWX).

AOL and Time Warner made their own wish list of potential directors earlier this year, but some people are also lobbying the company to join the board.

BoomTown is working on discovering all those names, but sources added that the candidates being looked at are a mix of personalities culled from the media, advertising and Web worlds.

Among the key attributes: More presumably fast-forward and innovative Silicon Valley types that can help burnish AOL’s tarnished tech cred.

Here are some of my picks:

Facebook COO Sheryl Sandberg, Guitar Hero CEO Dan Rosensweig, WordPress founder Matt Mullenweg (actually, AOL should buy the start-up), eBay (EBAY) CEO John Donahoe, LinkedIn Chairman Reid Hoffman or CEO Jeff Weiner, Juniper Networks (JNPR) CEO Kevin Johnson, Netflix (NFLX) CEO Reed Hastings, and former AOL iconic exec Ted Leonsis.

And, just for fun, News Corp. (NWS) digital don (and ousted former AOL head) Jon Miller or former Yahoo President Sue Decker.

(I might also add former AOL exec, Netscape co-founder and all-around entrepreneur Marc Andreessen, but if he joins another tech/Web board, he is going to get splinters.)

That’s because Armstrong has set a strategy centered around the turbocharging of online content, powered by a more flexible platform and paid for by goosing AOL’s graphical advertising business.

This puts the online icon–once a powerhouse and now not so much, having operated inside Time Warner since its merger early in this decade–in more serious competition with Yahoo (YHOO).

Yahoo now dominates content on the Web, with powerful news, sports and finance sites, and has recently been trying to reinvigorate its brand. This week, it launched a new marketing campaign with the motto, “It’s Y!ou.”

Yahoo also recently struck a search technology and advertising partnership with Microsoft (MSFT), which has now aimed its efforts at AOL.

According to sources, Microsoft execs have been aggressively courting AOL to switch its search business from Google (GOOG).

The search behemoth has long been AOL’s partner in what sources at both companies said has been a productive and lucrative relationship.

Armstrong is also a former top exec at Google, which many at the company hope will further cement its chances.

And while the renewal of that deal does not officially need to be struck until late next year, sources add that Google has already prepared and offered what it considers an attractive new deal for AOL.

But, much to Google’s chagrin, with a focus on the spinoff and preparations for some more cost-cutting in the months ahead, AOL has decided not to accept it yet and is not likely to anytime soon.

While hedging the situation in a recent video interview with MediaMemo’s Peter Kafka, Armstrong has also recently met with Microsoft execs, sources said, who have discussed a number of partnership options with him, including a tighter relationship with its MSN content properties.

“There’s no need to rush, especially since there is already a lot on AOL’s plate,” said one source close to the situation. “And, since it has options, AOL is going to take time considering them.”

(For more on Armstrong’s thinking, here’s a link to another video interview I did with Armstrong while both of us were in Germany today, in which he talked about the ad market and AOL’s strategy, but was cagey about being more specific.)

Please see this disclosure related to me and Google.

Several sources close to Yahoo and Microsoft have told BoomTown that a search partnership deal between the companies is more likely to be signed quickly now that Yahoo has picked former Autodesk (ADSK) CEO Carol Bartz as its next CEO.

Such a deal, which the pair have tried unsuccessfully to strike many times, would be a big boost to Bartz, who is coming into a very difficult turnaround situation at the troubled Internet concern.

Sources close to Microsoft (MSFT) said the company has readied its proposal to be floated to the Yahoo (YHOO) board. And CEO Steve Ballmer has been vocal in recent months about wanting to do a deal quickly.

“It’s ticked and tied,” said one person who has spoken to Microsoft execs of late and who predicted it could be signed as soon as Yahoo’s earnings report on Jan. 27.

Said another source at the software giant: “We’ve just been waiting for management clarity to move.”

BoomTown could not get further details about the proposal, but it is likely to be similar to past ones Microsoft has offered, with a small payment upfront and a long-term and large amount of guaranteed revenue.

Last June, for example, Microsoft offered Yahoo a hefty payday, as outlined in a letter from then-Microsoft exec Kevin Johnson.

He said Microsoft would have invested $8 billion in Yahoo at $35 a share, purchased Yahoo’s search assets for $1 billion and assumed the operations and R&D expense while returning data back to Yahoo for use in its advertising business. The two companies, Johnson noted, would have entered into a long-term search partnership, where Microsoft would have provided “favorable economics” to Yahoo search, including a three-year guarantee of higher monetization than Yahoo’s Panama paid search system currently provides.

While some on the Yahoo board, including Yang, remain on the fence about Yahoo essentially outsourcing its search business to Microsoft in exchange for a big pile of money, this seems to be the company’s only choice.

Bartz must also weigh in, of course, and she is someone who has more of an affinity for techies and might think Yahoo can continue to compete in what is turning into a pricey arms race in search between Microsoft and Google (GOOG).

In any case, most agree that a union is likelier than not, and is a question of when, not if.

Most importantly, after the failed takeover attempt of Yahoo by Microsoft, aimed at acquiring its search business, the pair have only lost more market share to the hugely dominant Google.

Yahoo’s attempt to strike a search deal with Google collapsed over regulatory concerns.

Given how small the Microsoft-Yahoo search combination is in comparison to Google’s market share of 72 percent, the two companies are less likely to encounter such difficulties.

With so many more ex-Yahoos out there now that the most recent layoffs have taken place, BoomTown put out feelers to a range of them to ask whom they would like to run the company they no longer work for.

After all, who better than to pick a new CEO than an ex?

The response I got was swift and varied wildly, depending on which way the ex-Yahoo felt the company should go, including quite a few who thought Yahoo needed to sell itself off completely.

Some considered Yahoo (YHOO) a media and advertising company, for example, while others thought of it as a more Web tools outfit. Still, others considered it a turnaround situation, requiring a wholly different kind of CEO.

Perhaps therein lies the problem–it is still hard to define precisely what Yahoo is and is not, even for its ex-employees.

In any case, here are some of the best suggestions:

1. The Media Mogul

“I think they need to sell to a media company,” said one ex-Yahoo, who posits the move needs to be drastic enough to truly reset Yahoo.

In this scenario, search gets sold to Microsoft (MSFT) and Yahoo’s online content is combined with media assets of a big entertainment and news conglomerate.

That would make the leader of Yahoo one of the following: Bob Iger of Disney (DIS); Rupert Murdoch/Peter Chernin of News Corp. (NWS); Jeff Zucker of General Electric (GE) unit NBC Universal; or Les Moonves of CBS (CBS). (News Corp. is the owner of this Web site.)

2. The Insider

A lot of votes here for former Yahoo COO Dan Rosensweig and not so many for current President Sue Decker.

Why? Several ex-Yahoos mentioned a need to refocus intently on products and the need for a product-obsessed leader, but one who also knew Yahoo well and could get things moving without needing a lengthy learning curve.

“Since Dan R. left, I think there’s been a definite void (at the senior exec level) on the product/consumer expertise and advocate front,” said another ex-Yahoo.

Other execs mentioned are former Yahoos Jeff Weiner and Jeff Mallett.

But several also pointed to board member John Chapple, who is the one most insiders say they are guessing will be the next CEO, especially since he has been reaching out to Yahoos on many levels and asking questions.

3. The Microsoftie or Googler

The new top name here is obviously recently departed online ad exec Brian McAndrews, former CEO of aQuantive, whom many think would be a strong pick and would focus the company on advertising.

In addition, most of those leaving–including several technical people–all seem to agree that Yahoo needs to get out of the search business, and pronto.

Said one engineer: “I hate to say this, but as good as we can be, we cannot compete in the war that is breaking out between Google and Microsoft. And it will only get uglier.”

Other names mentioned in this category include Yusuf Mehdi and Kevin Johnson of Microsoft, as well as Tim Armstrong of Google (GOOG).

4. The Fixer

While there are a lot of different opinions out there among the ex-Yahoos I spoke to, all agree that the company is in need of a sharp operator and someone who can do what it takes to turn the company around quickly.

That means someone like former Vodafone CEO Arun Sarin, whose name has popped up recently, or even nontechie execs known for operational skills.

“We need a decisive leader, given how slowly it takes for things to change at Yahoo, who has a real sense of urgency from the minute he or she gets the job,” said one ex-employee.

Another former exec described it as a “two-step process.” First, the turnaround CEO needs to come in and reorient, focus, and get the company going in the right direction, then a more product-oriented person can be installed under that CEO later.

5. The Holy Grail-Steve Jobs Option

I think the most interesting idea I got from all the many former Yahoos I spoke to was that Apple (AAPL) CEO Steve Jobs swoop in and buy Yahoo.

When I laughed out loud at this notion at first, the exec insisted that it was a feasible idea, given that Apple was interested in expanding its platform beyond its now-popular devices.

It’s an interesting bit of wishful thinking, of course, to imagine a “great leader” to calmly guide the company back to its roots.

Jobs, in fact, memorably addressed a meeting of Yahoo VPs in the fall of 2007. As I wrote then: “Jobs basic message [to Yahoo]: You have great assets–just like Apple did–and now it is all about execution.”

Yes, that tiny little detail.

6. Raise the Yangtanic

Interestingly, pretty much all the ex-Yahoos I talked to–as angry as some are at him for his tenure as a CEO less successful at execution and the ensuing loss of market value at Yahoo–said they did feel there was a need for Co-Founder Jerry Yang to stay around in a significant way.

“Jerry has been a really bad CEO,” said one former employee. “But he could still be an important leader at Yahoo and give the company the kind of inspiration it so desperately needs.”

Not everyone is on board with that.

“I completely disagree that Jerry should stay around. Jerry is one of the main issues at Yahoo and he and [David] Filo must go, as well as most of the board,” said one former Yahoo. “There needs to be free rein for the new CEO to make changes and that won’t be possible if Jerry is still there. Jerry is a nice guy and his heart is in the right place but he has failed as both board leader and CEO and the company needs to start fresh if it is to have a chance.”

Adds the ex-Yahoo: “Steve Jobs would be great, but I think he is busy.”

[UPDATED: H-P exec Todd Bradley has been a public company CEO, which I reflected below correctly.]

With Yahoo board Chairman Roy Bostock reportedly assuring investors and others that the company will have a CEO in place by the end of the year, it seems prudent for BoomTown to initiate an official Yahoo CEO Countdown.

After all, this column had a 100-Day No-Sacred-Cows Vision Quest to mark the time that Jerry Yang said he needed to give Yahoo a top-to-bottom look-see when he took over last summer as CEO.

Yang announced he was stepping down on Nov. 17, prompting the search for someone to lead Yahoo (YHOO) to the promised land where BoomTown countdowns are illegal.

But that’s not today, so here’s the 26-days-to-go update:

It looks like Yahoo has almost no chance to nab a top candidate, News Corp. (NWS) COO Peter Chernin. While Yang made nice and Bostock quickly lobbed in a call to get the well-known exec to come in and talk, several sources said Chernin declined even that.

Of course, moguls like Chernin are pros at not interviewing–one media player schooled me that you apparently never show interest in a job and only take it if a full offer is made, because if you don’t get it after chit-chatting, you look like a loser.

But I don’t think it is a slick feint on his part, even though Chernin is now engaged in contract renewal negotiations at News Corp. (which owns this Web site).

Consider: If you were Chernin, would you want to trade your powerful, well-paid, glamorous job in Hollywood and New York for what will surely be a slog of a job in Sunnyvale, and in a cubicle?

And Chernin has told many he is not interested in doing the job, although News Corp. would still love to do some sort of deal to combine its online assets, like MySpace, with Yahoo’s, as it almost did many times.

While Chernin did just take delivery on a Tesla, showing some clear geekiness, and he would be an exciting get for Yahoo, it’s the longest of shots.

The same is true for some other names that have been floated (by me!).

But several of the people are on the Yahoo board’s list too. And while things can change, it is more unlikely any of them will be the pick.

That includes former Yahoo COO Dan Rosensweig, who has a good life now as a media investor; former eBay exec and OpenTable CEO Jeff Jordan, who told his investors he does not want to be in the running and was sticking with the start-up’s IPO plans–if and when the economy recovers (although Yahoo could buy OpenTable and, thus, Jordan); former eBay (EBAY) CEO Meg Whitman, who could be running for governor of California; and former AOL CEO Jon Miller, who is not secretly buying Yahoo, but who could not be its leader anyway, since he is bound by a Time Warner (TWX) noncompete agreement until the end of March.

Another sticking point: The Yahoo board has limited the pool by a list of six criteria that it has drawn up, with the No. 1 being a CEO candidate has to have public company CEO experience.

If enforced, that nixes some folks, like Google (GOOG) exec Tim Armstrong. In addition, Yahoo President Sue Decker getting the nod is even more unlikely, for that and other reasons, according to many.

From my lists, that leaves DoubleClick head David Rosenblatt (his company is now owned by Google); Demand Media’s Richard Rosenblatt; former Viacom (VIA) head Tom Freston; former CNET CEO Shelby Bonnie; Hewlett-Packard (HPQ) exec Todd Bradley; and Juniper Networks (JNPR) CEO Kevin Johnson, who was the Microsoft exec who was key in the Yahoo takeover attempt there.

All have reasons not to either want or be able to take the Yahoo CEO job, so that means there could be a dark horse candidate. (I am now drawing up yet another list of qualified public CEO tech and media execs).

Here’s one: Yesterday, after it was announced he was stepping down from Microsoft (MSFT) in the wake of its hire of former Yahoo tech star Qi Lu as its online leader, I noted that I liked Brian McAndrews for the job.

Plus, the former CEO of aQuantive, which Microsoft bought for $6 billion last year, would be a delicious irony. But those who have talked to him told me McAndrews–who did want the digital head job at Microsoft and was left hanging by the software giant’s CEO Steve Ballmer–seems intent on taking time off now.

Alternatively, one of the two Yahoo board members, Maggie Wilderotter or John Chapple, both have the public company CEO checked off.

Personally, I am betting on one of them as CEO, although I believe it would be better if Yahoo picked a fresh outside choice.

So do a lot of execs remaining at Yahoo, most of whom visibly roll their eyes at the idea of a board member taking over, considering the record of the directors so far in guiding Yahoo’s fortunes.

That’s why the board–which definitely has not distinguished itself by any criteria so far in Yahoo’s long fall from grace–should try to get it right this time, as Yahoo can’t take any more of the way it has been running the show so far.

Former Yahoo tech star Qi Lu (pictured here) is poised to take on the big job of being Microsoft’s top digital executive, according to several sources inside and outside the company.

The appointment could be announced by Microsoft as early as next Monday.

A variety of details is still being ironed out, though, including whether the well-regarded techie Lu will be “paired” with another executive at Microsoft (MSFT) with more general business experience.

While Lu has managed large teams while at Yahoo (YHOO) and also huge projects, he does not have advertising sales and media experience that will be a big part of his purview at Microsoft.

In that job, he will be the boss of three strong digital execs at the software giant: Satya Nadella, the SVP who heads engineering for Microsoft’s search, portal and advertising platform group; Yusuf Mehdi, whose online services portfolio includes marketing, online audience business development and product management for MSN and the search properties; and Brian McAndrews, the SVP for the advertiser and publisher solutions group.

That executive partner could be some higher-ranking Microsoft exec or even CEO Steve Ballmer himself.

Elevating McAndrews is also a possibility, as he has also wanted the digital chief job and could decide to leave after not getting it. (He also would not be a bad choice for Yahoo’s new CEO.)

McAndrews was the CEO of aQuantive, an ad company bought by Microsoft for $6 billion last year.

As I have previously written, Lu would be a different choice for the post than many had expected.

In picking a serious tech-oriented executive over a more media-centric one, a dichotomy that Ballmer has been puzzling over, according to several people with whom he has spoken, he is clearly staking out an even more head-on fight with Google (GOOG).

But since a lot of Microsoft’s future rests on winning in the search and search-advertising space and trying to catch up with its techtastic Silicon Valley archrival from way back in the race, Lu is also well suited for the position.

Lu was EVP of engineering for the Search and Advertising Technology Group at Yahoo, where he ran all development initiatives for its search and monetization platforms. He was at Yahoo for a decade.

Importantly, Lu will definitely be a draw in bringing in top talent to Microsoft, especially from Yahoo.

Microsoft already grabbed another top Yahoo search exec, Sean Suchter recently.

And it is reportedly in a competitive bidding war with Google right now for yet another top Yahoo engineer.

Ballmer (pictured here), who led the now-defunct takeover bid for Yahoo and who has indicated a strong interest in buying only Yahoo’s search assets, could almost be seen as bypassing it all by sucking the talent right out of the place instead.

That might be a good move, since Yahoo’s board, while under intense Wall Street pressure to do so, is still debating whether to strike a deal with Microsoft to sell off its search and search ad business for massive guaranteed ad revenues.

While board member Carl Icahn has been pushing that deal, others on the board are still dubious that decoupling search from Yahoo is the right strategic move and believe it could leave the company at the mercy of Microsoft.

Yahoo might already be, especially if it keeps losing critical engineering talent to Microsoft. Being able to convince talent like Suchter and Lu to switch is a very bad sign.

Before he left Yahoo earlier this year, Lu was on the staff of the IBM Almaden Research Center, and worked at both Carnegie Mellon University and Fudan University in China (he also got degrees from both places).

And, in the kind of cred Microsoft likes, Lu holds 20 U.S. patents.

He left Yahoo after becoming dissatisfied with all the turmoil there, quitting in June, without another job lined up.

There has also been speculation that Lu would take a position as CTO of Facebook or even return to China for a tech job.

The well-respected Lu certainly has a multitude of choices, but the chance to lead money-laden Microsoft’s digital efforts–as it suits up for battle with Google–has been perhaps too hard to resist.

BoomTown has been poking around to try to figure out who Ballmer would choose for the digital head, ever since the man who used to be in charge, Kevin Johnson, departed in July for Juniper Networks (JNPR), after the software giant’s takeover bid to buy Yahoo failed.

I raised Lu’s name in a post several weeks ago as Ballmer’s top choice.

Several people close to the situation say the aggressive CEO has been keeping the deliberations close to the vest.

On an interesting side note, another one of Lu’s reports at Microsoft would be Harry Shum, corporate vice president of Search Product Development, who was his classmate and friend at Carnegie Mellon.

Please see this disclosure related to me and Google.

Here’s part of an internal memo BoomTown obtained about some small, but interesting, changes at Microsoft’s MSN unit, sent out by the GM of its Global Media Group, Greg Nelson, which is under the leadership of–well, frankly–a confusing panoply of execs.

Essentially, Nelson now reports to Satya Nadella, SVP of the Search, Platform and Advertising Group (think engineering and search) and Erik Jorgensen, Corporate VP of MSN (think business and other stuff).

In addition and apropos of nothing, Yusuf Mehdi serves as SVP of the Online Audience Business and Brian McAndrews is SVP of the Advertiser & Publisher Group.

Also, there is a Windows Live group that does mail, communications and groups too, and a lot of other digital bosses too numerous to mention.

You can see why I have been haranguing Microsoft (MSFT) CEO Steve Ballmer for a little digital clarity, especially around its consumer digital businesses and brands. But Microsoft–like a lot of tech-born businesses–loves to overdesign!

Ballmer has been searching for an overall head of that business to sort it all out since Kevin Johnson left in July, whose massive duties were divvied up.

While he has looked at a lot of execs from inside and outside the company, I recently posted that Ballmer’s latest quarry is former Yahoo tech star Qi Lu.

Only Ballmer knows for sure, many have told me, keeping his decision-making on the issue close to the vest.

But, as many insiders and outsiders familiar with the business have noted to me, whoever takes that role as its digital guru has some very hard decisions to make in all its arenas, from search to advertising to content.

There has been no share growth in search for Microsoft, for example, where archrival Google (GOOG) dominates, even as there have been billions of dollars of investment in data centers and engineers.

And it will fall to the person Ballmer ultimately selects as digital head to figure out what to do next.

Microsoft’s failed attempt to buy Yahoo (YHOO) was one way of dealing with the many issues Microsoft is facing, as well as its current interest in buying Yahoo’s search business.

In any case, here are some new changes at MSN, in Nelson’s words:

· Network Programming, led by Rob Bennett–This group will prioritize investments against Network priorities, shape audience strategy, set Network standards, and sponsor cross-network initiatives.

· Chief of Staff, Eva Corets–This role is responsible for driving team processes and business rhythm, and assisting with prioritization of network projects and interaction with cross-division and cross-Microsoft teams.

Yesterday, BoomTown opined that Microsoft was nearing a decision on who would become the head of its digital efforts.

And, according to several sources and some puzzling by me–if an agreement can be reached–I think that Microsoft (MSFT) CEO Steve Ballmer’s top choice is former Yahoo tech star Qi Lu.

While this is by no means a done deal, Lu is just the kind of top tech exec that Ballmer and Microsoft would warm to over a more media-centric choice like former Yahoo COO Dan Rosensweig or former AOL head Jon Miller.

Lu was EVP of engineering for the Search and Advertising Technology Group at Yahoo (YHOO), where he ran all development initiatives for its search and monetization platforms. He was at Yahoo for a decade.

If Ballmer manages to pull off the hire of Lu–on the heels of already grabbing another top Yahoo search exec, Sean Suchter, which I reported on yesterday–the aggressive exec could almost be bypassing a Yahoo search partnership he has long sought by sucking the talent right out of the place instead.

Ballmer is like Edward in “Twilight,” attracting top-notch search execs to Microsoft’s Redmond HQ, as if they were geek versions of Bella.

Lu would be a different choice for the post than many had expected, with a much more technical background than one in online media or advertising sales.

But since all of Microsoft’s future rests on winning in the search and search advertising space and trying to catch up with its archrival Google (GOOG) from way back in the race, Lu is also well suited for the position.

If Lu takes the job, he will be the boss of three strong digital execs at Microsoft: Satya Nadella, the SVP who heads engineering for Microsoft’s search, portal and advertising platform group; Yusuf Mehdi, whose online services portfolio includes marketing, online audience business development and product management for MSN and the search properties; and Brian McAndrews, the SVP for the advertiser and publisher solutions group.

Lu is known as as solid manager, but he is also called a very nice man and unusually humble for a tech star by many, which could be a good influence on Microsoft.

Before Yahoo, Lu was on the staff of the IBM Almaden Research Center, and worked at both Carnegie Mellon University and Fudan University in China (he also got degrees from both places).

And, in the kind of cred Microsoft likes, Lu holds 20 U.S. patents.

He left Yahoo after becoming dissatisfied with all the turmoil there, quitting in June, without another job lined up.

Since he left Yahoo, there have been rumors that he might be headed to Microsoft, but not in such a prominent job.

There has also been speculation that Lu would take a position at Facebook or even return to China for a tech job.

The well-respected Lu certainly has a multitude of choices, but the chance to lead money-laden Microsoft’s digital efforts–as it suits up for battle with Google–is compelling.

BoomTown has been poking around to try to figure out who Ballmer would choose for the digital head, ever since the man who used to be in charge, Kevin Johnson, quit in July, after the software giant’s takeover bid to buy Yahoo failed.

Several people close to the situation say Microsoft’s Ballmer has been keeping the deliberations close to the vest–perhaps because so many of those he has targeted have declined to consider the job.

But this week, many sources both inside and outside the company have told me that Ballmer is close to announcing his choice.

Annoyingly, one source has decided to play a digital version of “The Da Vinci Code” with me, dribbling out clues–more technical than media, very well liked in Silicon Valley, humble–about the candidate, which he wanted me to solve as if I were Robert Langdon and on the hunt for the progeny of Jesus.

Well, my solution is in: Microsoft’s most promising digital Holy Grail is Lu.

On a related note, bizarrely, the day after this column broke the story about Lu’s leaving Yahoo, I caught him by accident in the background of a video I was doing at a Harvard Business School event honoring Facebook’s Mark Zuckerberg.

You can see him at 4:14 minutes in the video, laughing at me, as I bother Greylock Partners VC David Sze and make a bad pun related to former Yahoo exec Jeff Weiner’s departure from Yahoo.

Here’s that video:

Please see this disclosure related to me and Google.

At least Yahoo got one day of stock euphoria, on the news that its CEO, Jerry Yang, was stepping down, before Microsoft CEO Steve Ballmer dropped yet another bomb on the troubled Internet giant by saying once more with feeling that he is not at all interested in buying it.

Yahoo (YHOO) stock plummeted on the news, dropping below $10 a share to close at $9.14, down $2.41 or an astonishing 21 percent.

While lack of interest in acquiring Yahoo is a sentiment that Ballmer has expressed more times than Alaska Gov. Sarah Palin said “maverick” in the presidential campaign, Wall Street continues to hold out hope that Microsoft might swoop in and make a new takeover bid for all of Yahoo.

It will not. Let’s repeat. It. Will. Not.

Thus, an obviously frustrated Ballmer reiterated his nondesire for Yahoo at Microsoft’s annual shareholders meeting, near its Redmond HQ today.

“We are done with all acquisition discussions with Yahoo,” Ballmer said. “We did our best…we’ve moved on.”

And so should investors, stock analysts and hedge fund vultures, who actually contact BoomTown on a daily basis, asking if when I wrote that Microsoft (MSFT) was not interested in buying Yahoo, I actually meant that it was interested.

Not interested means, well, not interested, except when it comes to those who wish fervently for a pop in Yahoo stock.

But the only way that is going to happen is slowly, as Yahoo rebuilds its much-battered business, brick by brick. And that presumably will happen when a new CEO is selected to run Yahoo.

Lucky for Yahoo, what Ballmer has repeatedly also said is that he was very interested in (and said again today) a search partnership deal with the company.

Microsoft essentially wants to take over that part of Yahoo’s business and will likely give it a pretty penny to do so. For all its troubles, Yahoo remains the No. 2 search player, well behind Google (GOOG), but well ahead of Microsoft.

Microsoft execs think grabbing Yahoo’s business will help it gain on Google–good luck with that, but it gets an A for effort!

And it also hopes another reorganization of its digital businesses will help it do so.

Right now, for example, newly annointed digital exec Yusuf Mehdi is deep in the midst of a restructuring of his division.

Mehdi’s online services portfolio at Microsoft now includes marketing, online audience business development and product management for MSN and the search properties, but divisions and execs are being shifted around.

But the big news, of course, will be the person Ballmer selects to be Mehdi’s boss, as well as the boss for Satya Nadella, the SVP who heads engineering for Microsoft’s search, portal and advertising platform group, and for Brian McAndrews, the SVP for the advertiser and publisher solutions group.

While Ballmer has taken his sweet time in picking someone, after Kevin Johnson left his post overseeing the division in late July, sources inside and outside Microsoft have told me the company is very close to picking a new head.

That would be a good thing since Ballmer has worn out his Rolodex trying–he has been turned down by many, including former Yahoo CEO Dan Rosensweig.

While I am trying to ferret out the current choice, sources said the main candidate is more technically oriented and is well known in Silicon Valley.

Please see this disclosure related to me and Google.

BoomTown might have been remiss in my post yesterday on top candidates for the Yahoo CEO job, after the news Monday that Jerry Yang is stepping down, by leaving out several key possibilities.

Yesterday’s roster included News Corp.’s Peter Chernin, Google’s Tim Armstrong, Kevin Johnson of Juniper Networks (JNPR) and also two Yahoo board members, among others. (The main internal candidate, Yahoo President Sue Decker, seems unlikely to get the nod.)

So here is an addendum to my initial list–all of whom are Yahoo (YHOO) outsiders.

Tom Freston:

Chernin is not the only media mogul whose name is being bandied about–the other prominent one is former Viacom head Tom Freston.

Freston apparently got shafted by the–let’s be polite here–disturbingly volatile founder of Viacom (VIA), Sumner Redstone, for not buying MySpace. In fact, News Corp. (NWS), which also owns this Web site, did. But Freston remains a well-respected and creative exec and has been dabbling in the Internet space since leaving Viacom.

Also, Oprah and Arianna love Freston–which is all I need to know.

Jeff Jordan:

Jeff Jordan, the former top eBay (EBAY) exec who is now the CEO of OpenTable, was also on the short list for COO at Facebook, a job that went to former Google exec Sheryl Sandberg.

While the restaurant reservations Web start-up has been headed for a public offering, that event has obviously been pushed out indefinitely by the econalypse, which might be just the impetus to convince Jordan that bussing tables all day is too dull.

Some speculate that Yahoo could buy OpenTable and get Jordan in the process.

Richard Rosenblatt:

Another interesting idea is Richard Rosenblatt of Demand Media, a company that Yahoo was sniffing around not too long ago.

The network of social-networking sites and apps maker is an innovative play in the space and might give Yahoo some much needed Web 2.0 DNA. Demand could still be bought by Yahoo, in order to put Rosenblatt into place.

(Rosenblatt, for those who do not remember, ran the company that owned MySpace, and he was key to selling it to News Corp.)

Also, Lance Armstrong likes Rosenblatt.

Shelby Bonnie:

A reader actually made the excellent suggestion of former CNET head Shelby Bonnie, who is now investing in start-ups. Bonnie is another steady exec–despite leaving CNET, now owned by CBS (CBS), under an options backdating controversy–and is well-liked in the Internet industry.

Yahoo would be a much bigger job than he has ever held, although he certainly has both tech and advertising experience online.

David Rosenblatt:

Lastly, especially if Yahoo is interested in an exec who has turnaround talent, there is probably no better a choice than DoubleClick CEO David Rosenblatt. An experienced online advertising exec, he is also sharply outspoken and knows how to get companies in line and fast.

He is also impossibly rich after Google (GOOG) bought DoubleClick out from under–wait for it–Yahoo recently. While he is still running the show for Google, after having decided to stay, Yahoo might present an interesting challenge for the very savvy Rosenblatt.

Please see this disclosure related to me and Google.

And, no surprise, he is the No. 1 choice of most inside and outside Yahoo (YHOO) in the wake of the news late yesterday that current CEO and Co-Founder Jerry Yang is stepping down.

And why not? Chernin has the right resume: Experienced at running large and complex organizations; savvier than most in media about the Internet; able to make the kinds of dramatic decisions needed; and, perhaps best of all, signaling–via the Los Angeles Times–just this past week that he was open to leaving the powerful media and entertainment conglomerate for something new.

Well, Yahoo would certainly be new for Chernin, in terms of a corporate cleanup challenge, especially compared to figuring out how to make bank on plush toys from “The Simpsons.”

And, while the risks are many, if Chernin (pictured here) managed to turn around Yahoo, he could make a huge fortune too, given Yahoo shares have languished of late, much in the same way they did when former CEO Terry Semel came to Yahoo from Hollywood in 2001.

But it’s not altogether clear whether Chernin would actually leave his powerful perch at News Corp. (NWS)–which owns Dow Jones and owns this Web site. He has been ensconced there for a dozen years, building a huge reputation as a sharp exec (No, Peter, I am not kissing up, as I think Yahoo would wear even you down very, very quickly).

That’s even though many note he is not likely to take over as CEO from its iconic leader, Rupert Murdoch. The media mogul is widely expected to favor one of his own children to lead News Corp. next.

And the 57-year-old Chernin already makes close to $30 million in his current job, which is definitely challenging.

And, although Chernin has been involved in the News Corp.-owned MySpace and has had success backing the Hulu online video site, it is not nearly as hard as the five-year turnaround quagmire (plus no fabulous media mogul perks either) that Yahoo could turn out to be.

In addition, privately to other News Corp. execs, Chernin has regularly pooh-poohed a move to a digital company, even though he is always on the short list for a lot of big Internet jobs–such as the long-unfilled post as digital head at Microsoft (MSFT) more recently.

So, who else to take over from Yang, who will return to his job as Chief Yahoo after stepping down from the company as soon a search for a replacement CEO is successful?

Well, here is BoomTown’s own shortish list, based on asking a wide range of people inside and outside Yahoo, all of whom are important digital players in their own right.

INSIDE YAHOO

Sue Decker:

The current President of Yahoo is certainly being “considered” for the job, which is a polite term for not really being considered at all. While Decker is an intelligent and thoughtful exec, like a politician with a record, she has had her hand on the operating tiller at Yahoo for too long not to get deservedly blamed for its current situation.

In addition, she is radioactive to big investors, who have told the Yahoo board in no uncertain terms that she is a nonstarter.

Maggie Wilderotter:

The former Microsoft exec, who has also been a public company CEO, is an interesting idea floated by some, who think the Yahoo board might turn to one of its own directors, as a short-term solution to stabilize Yahoo.

Wilderotter has been much focused, said several Yahoo execs, on cost-cutting at Yahoo and certainly is not as tarnished, being a more current board member. But she is a largely unknown quantity in the Internet space and, most importantly, at Yahoo.

John Chapple:

The former CEO of Nextel is one of the two board members (former media Frank Biondi Jr. is the other) recently picked by Carl Icahn, when the activist shareholder was admitted on the board as part of the proxy fight settlement.

Chapple has, sources said, been conducting chats with Yahoo execs lately, perhaps as a way to get a lay of the land. If he got the job, it would be clear Icahn had won his Pyrrhic victory (and personal financial defeat) against Yang.

OUTSIDE YAHOO

Dan Rosensweig:

The very funny, but brash, former Yahoo COO is definitely a favorite within Yahoo’s ranks, except for those who don’t like him. But it’s clear Rosensweig does know and love Yahoo, is close to Yang and, ironically, enjoys a tight relationship with Microsoft CEO Steve Ballmer, who also wanted him for the digital head job.

Also, Rosensweig, who does have operating chops, has gotten some much needed time away from Yahoo, as a partner at the tony media investment firm, the Quadrangle Group.

Meg Whitman:

Another dreamy CEO choice, except she has already been a big company CEO at eBay (EBAY), has proved her mettle in building it to a powerhouse–despite the online auction site’s currently harder times–and has the giant fortune to prove it.

And, oh yes, she is likely to be using that pile of cash to run for governor of California, on the Republican ticket.

Jon Miller/Ross Levinsohn:

The Bobbsey Twins of the Internet, the pair are now having a very good time running their own investment company, the Velocity Group.

But, aside from some questioning whether he can make the quick decisions needed at Yahoo, Miller (pictured here on the right), the former head of AOL, does not want to leave his New York home and cannot take any job anyway until his noncompete with Time Warner (TWX) runs out in March.

And former Fox Interactive Media head Levinsohn likes Los Angeles, and probably is too fast a personality for Yahoo (his going there would be a shock to its system, but would be endlessly entertaining to me personally).

Tim Armstrong:

The top ad exec at Google (GOOG) certainly is an interesting idea, although has little of the product experience needed to run Yahoo. But he is a well-respected advertising figure–where Yahoo needs to shine–and could do well with a lot of strong execs under him.

He is also not on a CEO path at Google–paging, Larry Page!–and could be interested in proving he could run a company on his own.

Kevin Johnson:

The former Microsoft exec was supposed to be running Yahoo, if he and Ballmer pulled off their takeover attempt earlier this year. They did not, and Johnson then left Microsoft to run Juniper Networks (JNPR) in Silicon Valley, right up the road from Yahoo, in fact.

But Johnson is likely subject to a noncompete by Microsoft and a strong contract at Juniper too. Still, a very sharp exec, he definitely has the operating, political, technological and digital skills to take on Yahoo. Also, ironically, he and Yang really get along well and like each other, despite the takeover battle.

Of course, there are a lot of other ideas: Disney (DIS) online exec Steve Wadsworth; the outside-the-box choice of former Procter & Gamble (PG) marketing wizard Jim Stengel; Microsoft digital exec Yusuf Mehdi; CBS (CBS) digital head Quincy Smith (whose hyperactive dealmaking would likely lead to a mutant merger between CBS and Yahoo); and former Cisco (CSCO) and current Joost CEO Mike Volpi.

Please post suggestions below or, better yet, send tips to me at here.

Please see this disclosure related to me and Google.

Yahoo CEO Jerry Yang will step down from his job as CEO as soon as the board finds a replacement for him, in what sources close to the situation call a joint decision by him and the company’s directors.

Yahoo (YHOO) will announce the move within the next hour. [UPDATED: Yahoo confirms the move in its official press release.]

But, in a memo to Yahoo’s employees, obtained by BoomTown, Yang confirmed the pending departure, writing: “…we believe the time is now right to transition to a new ceo who can take the company to the next level.”

Yahoo has hired Heidrick & Struggles, the well-known executive search firm, to evaluate candidates, both internally and externally.

After a replacement is found, which the company hopes will be quickly, sources said, Yang will resume his former title as Chief Yahoo and will also remain on the Yahoo board.

While did-he-walk-or-was-he-pushed speculation will no doubt run rampant, sources said Yang already has and will play an important role in the search for his replacement.

Sources close to the board expect the choice will end up being an outsider and is not likely to be current Yahoo President Sue Decker, although she is being considered for the job.

But both she and Yang have been closely affiliated with each other as the company has struggled to right itself after a tumultuous year and its stock price has plummeted.

Yahoo shares closed today at $10.63 after trading at historic lows for a while and giving the company a valuation of only $14.7 billion.

While Yahoo’s board has some execs in mind to become CEO, obvious candidates include News Corp. (NWS) COO Peter Chernin, as well as former AOL head Jon Miller, former eBay (EBAY) CEO Meg Whitman, Google (GOOG) ad exec Tim Armstrong, former Fox Interactive exec Ross Levinsohn and former Yahoo COO Dan Rosensweig (who is currently with the Quadrangle Group).

BoomTown would also throw in former Microsoft top exec Kevin Johnson, now CEO of Juniper Networks (JNPR), and who led the software giant’s abandoned takeover bid against Yahoo earlier this year.

According to sources, both Yang and the board have been discussing the move for months, although Yang has been saying quite explicitly in public that he was going to stay in place to see through the many changes he has made in his 16-month tenure.

In a recent interview with me, in fact, Yang said about his determination to lead:

“In this uncertain environment, I think I am absolutely the right person. Times like this require a leader who really understands this company and its customers, and I think I do. The world is a different place today than even a month ago and I think I am the best person to guide Yahoo through this volatile time.”

In fact, it has always been a volatile time for Yang at Yahoo. He took over suddenly last June from former CEO Terry Semel, whose departure also came after Yahoo’s struggles became increasingly apparent.

Things only got worse for Yang, due to both his own and previous management missteps and also massive external forces, including a hostile takeover attempt by Microsoft (MSFT), which was soon followed by a proxy fight by activist shareholder Carl Icahn.

The Microsoft bid–which was $31 a share–was abandoned, and Icahn dropped the proxy fight, with Icahn joining the board with two other directors he had handpicked.

And while Microsoft has been interested in a deal related to Yahoo’s search business, its CEO, Steve Ballmer, has categorically ruled out a renewed bid.

Yahoo also saw its search business decline in the face of dominance in the market by Google (GOOG), which had ironically started its then-nascent business on Yahoo as its search partner.

Worse still, Yahoo’s strong graphical ad business has suffered badly in the midst of the current economic meltdown.

There has also been an exodus of major executives over the last year, along with recently announced layoffs of 10 percent of the company, which are set to take place Dec. 10.

In addition, Yahoo’s controversial search ad deal with Google collapsed and its talks to merge with Time Warner (TWX) online unit AOL have dragged on.

With all this, sources close to the company said that both Yang and the board felt the company needed another leader to take it to the next level and complete the turnaround efforts Yang has been trying to pull off.

“It was time for someone else,” said one source close to the board.

More, obviously, to come…

Please see this disclosure related to me and Google.

The company has been on the lookout for the person to lead its online efforts ever since the exec formerly in charge, Kevin Johnson, headed out in late July, after the Yahoo takeover bid failed.

At the time, Microsoft CEO Steve Ballmer promised a quick search for a Web leader the software giant has so sorely needed.

But, apparently, quick means not-so-quick at Redmond HQ, where Ballmer has had a few other things to deal with (like the vagaries of Windows Vista!). So, he has cast about for more than three months, both internally and externally, for the person who will turbocharge Microsoft’s Web efforts.

Sources said Ballmer continues to look for an external candidate to save the day, as he has been, preferring an outsider to give the division some spark.

And, while well-known Internet figures like former Yahoo COO Dan Rosensweig, former AOL head Jon Miller and former Facebook exec Owen Van Natta have all taken a pass, Ballmer is soldiering on.

New prospects include former Cisco exec and current Joost CEO Mike Volpi, sources said, with whom Ballmer is likely to be chitty-chatting next.

BoomTown likes that choice, given Volpi has both technical and deal-making skills, and he is someone well-liked in both media and Internet circles. In fact, Volpi has also been a favorite of Yahoo CEO Jerry Yang, who would also dearly love to snag the personable exec.

But Joost, the once-hot online video start-up, has just pushed the restart button with its new flash player, and is hoping to live up to its initial hype, especially in the wake of the success of rival Hulu.

So it is not entirely clear that Volpi would leave at this moment.

Other possible outside digital execs with the right experience are few and far between.

If I was making a list, I would include CBS Digital kingpin Quincy Smith (who probably talks too quickly for Ballmer), as well as Google ad head Tim Armstrong, although both are also unlikely to move from where they are ensconced.

Thus, with so few good choices, it might be that Microsoft (MSFT)–as usual–turns inward.

But even that’s in question, given the prospects of the main internal candidate, Brian McAndrews, who came to Microsoft in its acquisition of aQuantive and runs its online advertising business, seem to have dimmed, sources said. But some caution that McAndrews is not out of the running yet.

The other insider with a chance–Yusuf Mehdi–got the job running MSN and other of Microsoft’s online properties.

He is waiting for the digital uber-boss to lead him, as well as McAndrews and also Satya Nadella, the SVP who heads engineering for Microsoft’s search, portal and advertising platform group.

For now, said one source, that appears to be Ballmer. “He’s going to be the digital chief,” joked one exec. “Until he finds someone he likes just as much.”

In any case, here is a recent interview I did with Volpi in London about Joost’s restart:

Longtime Microsoft exec Yusuf Mehdi (pictured here) is taking over a big part of Microsoft’s online services portfolio–including marketing, online audience business development and product management for MSN and the search properties.

But Microsoft (MSFT) has yet to name an overall digital head for these online properties, which has been promised by Microsoft CEO Steve Ballmer since the departure of Kevin Johnson in late July.

Mehdi is essentially getting a part of the portfolio of Microsoft SVP Bill Veghte, who will now be primarily focused on Windows and Windows Live business groups.

Mehdi was previously the SVP for strategic partnerships under Johnson.

He is now part of a troika that includes Brian McAndrews, the SVP for the advertiser and publisher solutions group, and Satya Nadella, the SVP who heads engineering for Microsoft’s search, portal and advertising platform group. (Both are pictured here, left to right.)

Who will lead this three-headed beast is still unknown–both Mehdi and McAndrews have been considered the top internal candidates to lead the online properties group, which has been struggling for direction after Microsoft’s failed takeover of Yahoo (YHOO).

Yahoo’s shares have plummeted in recent days, as Wall Street has been hard hit, closing at just below $17 a share today, with a market cap of almost half of what Microsoft’s initial offer was early this year.

To stir things up and catch archrival Google (GOOG), Ballmer has reportedly been trying to recruit a superstar exec from outside the company, including Silicon Valley, to no avail.

Time waits for no man–but Microsoft CEO Steve Ballmer seems to be taking an awful lot of it in picking who will head the software giant’s long-foundering digital efforts.

It has been almost two months since Microsoft said it would find someone to helm the part of the business that was run by former exec Kevin Johnson, who left in July after the software giant’s bid for Yahoo failed.

A decision could come at any time, although Ballmer is reportedly intent on getting exactly the right person for the job.

But, by now, most inside the company had expected him to make the most obvious internal choice of SVP Brian McAndrews, who came to Microsoft (MSFT) via its $6 billion acquisition of aQuantive.

McAndrews now runs Microsoft’s Advertising and Publisher Solutions Group.

Longtime digital SVP of Strategic Partnerships Yusuf Mehdi has been seen as the No. 2 candidate. He could also be part of a team that includes both him and McAndrews.

Many sources have said they expect McAndrews to leave if he is not given the top digital post.

But sources also report that Ballmer remains more intent on hiring someone outside the company, with the idea that such a person could better re-energize Microsoft’s moribund Internet efforts and bring in a fresher perspective.

According to sources, his favored external pick has been former Yahoo (YHOO) COO Dan Rosensweig, who has turned down the offer.

Ballmer has also been interested in former Facebook top exec Owen Van Natta, who might be a dark horse in the race.

In addition, Ballmer has previously queried former AOL head Jon Miller, who was in line to be on the board of Yahoo until he was nixed due to a noncompete agreement with the online service’s owner, Time Warner (TWX). Miller told Ballmer he was not interested in the job.

“Ballmer is burning up the Rolodex and coming up empty,” said one person familiar with Microsoft. “But he is still looking outward.”

Other sources said Ballmer (pictured here) might now be considering a more pure-tech exec for the role, rather than a Web exec.

Microsoft’s culture is more technical than not, and such a leader might have an easier time leading the company’s Web efforts.

Yesterday, Valleywag had an intriguing report that well-regarded former Yahoo tech exec Qi Lu, who was its top search scientist, might be headed to Microsoft.

But Lu would be a more powerful weapon in Microsoft’s fight with archrival Google (GOOG) in the search arena than as the company’s overall digital leader.

Then again, nabbing someone like Li could be part of a larger team Ballmer might be contemplating, made up of both external and internal elements.

Time will tell, of course. How much time, though, is anyone’s guess.

There will be a lot of different reactions to the first of Microsoft’s newest series of commercials, featuring Founder Bill Gates playing straight man to comic Jerry Seinfeld.

Set up as a discount shoe-buying skit, Seinfeld helps Gates purchase a pair called “The Conquistador,” and for some Seinfeldesque reason, it’s churros all around.

Actually, it feels a lot like the frequent and excellent Microsoft internal spoof videos Gates does with various celebs.

I have always liked them a lot and I like this one too, as it is quirkily charming (or is it charmingly quirky?).

But I am not sure the Gates-Seinfeld kibitzing will really get a lot of people talking about Microsoft (MSFT) products, as is the marketing goal.

And they surely are no where near as spot-on as Apple’s famed PC-Mac guys commercials, which are memorable and witty and deliver the message that Apple (AAPL) products are better.

What might be more effective, of course, at least in the Internet arena, is for Microsoft to get off the stick and lay out its next Web strategy clearly, especially in the wake of its failed attempt to acquire Yahoo (YHOO), and name the digital chief it said it planned to.

Several sources with knowledge of the situation expect an internal choice to helm the part of the business that was run by former Microsoft exec Kevin Johnson, who left after the software giant’s bid for Yahoo failed.

Although an external star coming in would be CEO Steve Ballmer’s top choice, I would guess, top internal contenders are Brian McAndrews, who came to the company via its $6 billion aQuantive acquisition, and longtime exec Yusuf Mehdi, who was Johnson’s strategy guy.

(BoomTown votes for a combination of both to make it extra complex!)

In any case, if it is serious about taking on rival Google (GOOG) in the online ad space and becoming at least the No. 2 player in the market, Microsoft has to move sooner than later and definitely much faster and it has a lot of options.

With Yahoo’s stock circling the drain, closing yesterday at $17.75, will Microsoft think about another bid for even a part of the Internet company?

Or will it try, as it claims, to get truly serious about building its business organically with programs like Live Search cashback, a deeper focus on vertical search improvements in places like video, images and mapping, and more content on its MSN sites?

Or should it be aggressively looking around for other properties to purchase to bolster its Web assets, such as the company that owns the Ciao price comparison and online shopping sites in Europe, for which it just forked over $500 million?

Of course, Microsoft will likely keep trying all of these, although I hope not in the muddling way it has behaved for far too long.

Johnson was entirely right in his internally controversial concept that being one of the top players on the Web is key to Microsoft’s future, even more than its lucrative Windows software hegemony.

(If you want to read an interesting take as to why, don’t miss New York Times columnist Joe Nocera’s “Does Windows Still Matter?” post yesterday).

And with Google’s new foray into the browser business this week, Microsoft surely has to be certain that it does not lose in the one place it does dominate.

In other words, Microsoft has a lot of work ahead of it, well beyond amusing us with Gates doing a thankfully hands-free adjustment of his boxer shorts.

In any case, you should see that, so here’s the first Gates-Seinfeld commercial:
