Last year, Yahoo EVP Hilary Schneider and then-Media Group head Scott Moore had a summery seaside dinner with Demand Media co-founder and CEO Richard Rosenblatt (pictured here) in Santa Monica, Calif., right around the corner from the online publishing company’s HQ.

While many speculated that Yahoo (YHOO) could be doing some friendly kibitzing to get a sense of where the eclectic network of general- and special-interest sites was headed, for a possible acquisition, nothing came of it.

That’s because at the time, Rosenblatt insisted that he was aiming to eventually take his company public and Yahoo was in the midst of ongoing corporate turmoil.

“There is a lot of potential here and I want to build a big company for the long-term,” said Rosenblatt in an interview with BoomTown last July (see video below).

But, as my post noted: “Still, at some point when Yahoo is not in the free fall it is currently in, Demand might make a great purchase for Yahoo.”

And now, a year later, as new Yahoo CEO Carol Bartz works to stop that slide, several sources close to the company tell me another look-see at Demand is likelier than ever.

That’s underscored with recent indications that a major strategy will finally follow through on making Yahoo’s massive but disparate service more social, especially its content offerings.

But would Bartz go as far as making a big buy now or would she be more likely to strike a massive partnership with Demand, from which Yahoo could learn a lot?

Such an acquisition could cost anywhere from $1.5 billion to–as was floated last year in better times–$3 billion. In addition, if Demand was to engage in more serious talks with Yahoo, there would likely be other suitors.

As costly as that is, some sort of link-up with Demand is an interesting idea, especially since Yahoo could use a bold and definitive move to signal social goals that play to its strengths and are not a copycat of more powerful social-networking sites now in place.

At a Morgan Stanley (MS) conference last month, Bartz said, for example, that “I do not believe we can invent the next Facebook,” while noting Yahoo still needed to be more social throughout the service, especially in its content.

And, just yesterday, a Reuters article about that focus was titled: “Yahoo’s Plan: Create Community from Isolated Sites.”

Said the article: “If [Yahoo co-founder David] Filo and new CEO Carol Bartz have their way, the kinds of social networking features available on Facebook will become part of many Yahoo websites and allow their users to network with each other without using Facebook. The company hopes the strategy will help link its disparate properties, bringing more advertising dollars and growth.”

And that’s just at the heart of Demand Media, which dubs itself the “leader in social media.”

Demand was founded in 2006 by Rosenblatt and Shawn Colo, who raised a giant pool of funding–$355 million–from gold-plated investors like Goldman Sachs (GS), Oak Investment Partners and even a private investment from major Yahoo investor Gordon Crawford.

Getting that kind of backing was due to Rosenblatt’s entrepreneurial track record.

As founder, chairman and CEO, he sold iMALL to Excite@Home for $425 million in a 1999 stock swap.

And, perhaps most famously, as CEO of Intermix Media, Rosenblatt sold it with the company’s crown jewel, MySpace, to News Corp. (NWS) for $580 million in cash.

Then, Rosenblatt started Demand, which takes user-generated content of all kinds and on all kinds of topics–especially via video–from an army of freelancers and leverages it into massive traffic that it monetizes.

Demand is also the one of the bigger suppliers of video to YouTube, which it also monetizes.

And, through the acquisition of Pluck, the company also laces social-networking tools throughout the sites, as well as for many well-known third parties.

All this has given Demand upward of 70 million unique visitors per month, at sites like eHow and GolfLink.com, with about $150 million in annual revenue.

And–drum roll please–it is reportedly profitable, although how much is not clear.

While he has long maintained a public offering was on the horizon, despite the weak economy, Rosenblatt has also been interested in the idea of how to revive major players like Yahoo and Time Warner (TWX) online unit AOL.

Both have been struggling, but still have massive traffic and brand recognition, along with large advertising businesses.

And in many ways, the energetic Rosenblatt is just the kind of product-centric and visionary exec Yahoo lacks, despite Bartz’s clear ability to get the company’s management ducks in order.

What could be even more interesting, said one source, would be to marry Yahoo and Demand with a lot of what is going on with the publishing of niche sites at AOL’s MediaGlow content unit, in a giant publishing network.

Ironically, AOL was another acquisition target of Yahoo, in yet another deal that did not pan out last year.

Here’s the interview with Rosenblatt at Demand Media HQ last year:

When I was in Manhattan recently, I made a lovely visit to the world HQ of Andy Plesser’s Beet.TV, where we discussed where online video is going.

As some know, this is a big topic for BoomTown this year because the Web is clearly becoming a video-heavy medium.

And the ever-affable Plesser does a solid job covering it. This past week, for example, he looked into everything from the Web sites of the Presidential candidates to Reuters’s (TRI) video reporting of the escalating fighting in the South Ossetian town of Megvrekisi to a Canadian video-sharing site.

Of course, he does a lot of video about it all.

Here is my video interview with him and below it is a video he did with me in New York about the AllThingsD and D empire, right when I was doing the video of him (logrolling in our time!):

Tonight, The Wall Street Journal and Reuters had nearly identical stories, noting that Microsoft (MSFT) was interested in buying Yahoo’s (YHOO) search business, which–oh, we bloggers get so touchy when we don’t get even a smidgen of credit, don’t we?–BoomTown speculated was just what the software giant was interested in yesterday.

Wrote BoomTown on Sunday afternoon:

Will Microsoft now just buy Yahoo’s search business instead of the whole company?…The software giant would not give details, but sources at both companies speculated to BoomTown that it involved Microsoft buying Yahoo’s search business and the ad business related to text-based ads, or doing another kind of transaction that would bring the companies closer together to fight Google (GOOG)… Indeed, given that Microsoft, in its long-running war with archrival Google, it wants most of all to grab Yahoo’s search ad business to become a credible No. 2 in the important sector. It could do this via a purchase of those assets or, said others, formulate a deal to be Yahoo’s exclusive search partner.”

And wrote Reuters tonight:

Microsoft Corp. has proposed to buy Yahoo Inc.’s search business and take a minority stake in the Web pioneer, stopping short of a full-out merger, a person familiar with the discussions said on Monday… The new deal, if completed, would forge an alliance between the two companies that would represent an alternative means of competing with rival Google Inc., whose ubiquitous search engine has made it an online advertising powerhouse.”

Said The Journal in its new report, after focusing on a simpler Microsoft-Yahoo outsourcing deal Sunday, also tonight:

Microsoft Corp.’s proposed alternative to acquiring Yahoo Inc. would involve a break-up of the Internet giant that people close to Yahoo said is unlikely to win favor with its board. In recent days, Microsoft floated a proposal to acquire Yahoo’s search-advertising business, said people familiar with the matter… Microsoft’s proposal didn’t offer much detail on how it would structure a search-ad deal, the people said. But the plan would likely involve Microsoft’s selling the ads that appear alongside Web-search results delivered to Yahoo users; that could help it gain on Google, the search-ad-market leader.

To be fair, both Reuters’ and The Journal’s reports make such a plan by Microsoft even more definitive and have interesting new details, which are intriguing.

They include:

Both take note of Microsoft’s proposed sale of Yahoo’s Asian assets (worth close to $10 billion, according to the same analyst cited by both reports, who also puts a $21 billion value on Yahoo’s search ad business).

Reuters underscores that billionaire investor Carl Icahn is not pleased with the idea of a partial sale of Yahoo to Microsoft and might side with a Google outsourcing deal, if that came to pass.

And The Journal stressed that Yahoo’s board, which thinks it is all a Microsoft ploy to scotch a possible search-ad outsourcing deal with Google, was also unimpressed with Microsoft’s ideas.

More new news too from Om Malik at GigaOm, who gets hold of yet another Microsoft exec’s memo to the troops.

Yesterday, it was a “leaked” memo from Kevin Johnson, president of Microsoft’s Platforms & Services division.

Today, one from Satya Nadella, its VP of Search. In the memo, Nadella outlines some minor management re-orging, but mostly talks somewhat opaquely about where search is going (no wonder Microsofties are confused as to what direction to take!).

Money quote:

One of the clear themes that emerged from my discussions was the need to build depth of expertise and focus on both the media and technology side and connect the two via common purpose and vision. The other major theme was to create an organization that wherever possible helped drive global and cross network capability, while always enabling and empowering the local aspects of our media business. Lastly it’s imperative that we set up for blurring of the lines between Portal and Search to drive experiences that enable more seamless exploration of content across the search-browse continuum. We want the combined expertise of the team to drive this innovation and also create more scale with vertical efforts.”

A free lunch at AllThingsD.com HQ–come to my house, walk through the kitchen to the cottage in the back–for anyone who can explain this in easy-to-understand words to BoomTown!

Added challenge: Nadella can enter the contest too!

And, finally, don’t miss this report by TechCrunch about former Yahoo Chairman and CEO Terry Semel’s appearance at a conference in Israel on a stellar panel with Google’s Sergey Brin, Yahoo’s current President Sue Decker, News Corp. (NWS) head Rupert Murdoch and well-known Israeli entrepreneur Yossi Vardi.

All I can say is ouch at some of the translated highlights.

No, not as the conquering hero of Yahoo yet, but to give a talk to students at Stanford University about topics Gates often focuses on.

In a speech titled “On Software, Innovation, Entrepreneurship and Giving Back,” Gates will address the young folks gathered tomorrow afternoon at Stanford’s Memorial Auditorium, as well as to a contingent of media. And he will do a question-and-answer session with only students.

A temporarily muted BoomTown will be there, so here’s a shameless offer to any hoodie-wearing student: Free latte to anyone who asks Gates about the Yahoo bid.

Actually, we kid. That’s because Gates actually spoke out on the issue yesterday in an interview with Reuters.

While the software giant’s founder and chairman has taken a back seat to CEO Steve Ballmer in the Yahoo bid, Gates wasted no time in tempering expectations if Microsoft (MSFT) failed in its effort to buy Yahoo (YHOO).

Calling the Yahoo offer “very fair”–uh-oh, maybe the $35-per-share offer is not in the mail–Gates insisted the company would continue to invest copiously in search to try to catch rival Google no matter what.

“We can afford to make big investments in the engineering and marketing that needs to get done,” Gates told Reuters. “We will do that with or without Yahoo.”

But Gates also threw Yahoo a tasty compliment, noting: “But we also see that we’d get there faster if the great engineering work that Yahoo has done and the great engineers there were part of the common effort.”

And that’s got to be worth, in the wise words of J. Wellington Wimpy, at least a few samoleans.

(Completely unrelated factoid, except as it pertains to Wimpy: Gates loves hamburgers too, especially In-N-Out Burger, and has been known to seek the chain out when traveling down south of Seattle.)

Indeed, the future of the digital news business is entering a new phase with the two deals. Reuters agreed to be acquired earlier this year by Thomson for a little over $17 billion.

So I went to see Glocer in London to talk to him about what the merger means and also what new trends will be key. Glocer turned out to be a closet geek, a blogger and an unusually wide-ranging thinker on digital topics (especially for an ex-lawyer!).

In the video, he discussed trends like social networking, the continued importance of brands online and the future of Thomson-Reuters, which he said he hoped would become the “media company of the 21st century.”

Here’s the video, along with a short tour of Reuters’ HQ in the Canary Wharf section of London:

The combination of the second and third largest makers and distributors of financial information, news and other data (Bloomberg is No. 1) makes it a key player in the space. Besides news and photos, the company is a critical one in supplying banks, brokerage firms and investment firms with data, prices and other tools.

Being first and fastest with the right technical tools is going to be key for Glocer and Thomson-Reuters going forward, as it faces strong rivals and an ever-more demanding customer base, both in the free and premium online markets.
