There was no doubt, given the continuing economic collapse and all the joy that brings, that Demo09 was going to be a much tamped-down and sober affair this year.

But there are still a lot of interesting start-ups being featured in the main ballroom and demo “pit,” such as a cool “touch book” offering, a strange hooking-up-in-a-bar smartphone app and a plethora of ideas that obviously got their inspiration from the iPhone from Apple (AAPL).

As in: touch, swipe, interact! (Which is the official BoomTown motto, in point of fact.)

Demo Executive Producer Chris Shipley is still running the show. But VentureBeat founder and Editor-in-Chief Matt Marshall will take over the longtime, semiannual conference–where several dozen start-ups strut their stuff in front of an industry crowd–in 2010.

Here is the video I did of the event, which was held in Palm Desert, Calif., and ends today. It includes serial entrepreneur Mitch Kapor, PR guy Brian Solis and All Things Digital Co-Executive Editor Walt Mossberg.

This past weekend, BoomTown revved up the Mini and headed out in the pouring rain to a Peet’s Coffee in Fremont, Calif., to the exact spot where Demo Executive Producer Chris Shipley proposed that VentureBeat founder and Editor-in-Chief Matt Marshall take over the longtime, semiannual conference where several dozen start-ups strut their stuff in front of an industry crowd.

Shipley will still be running the show at Demo09 starting Sunday in Palm Desert, as well as the next Demo in the fall, with Marshall working alongside until he takes over fully in 2010.

(Shipley will remain on the advisory board, but will mostly be focusing on her consulting firm, Guidewire Group. She has run Demo for 13 years.)

Shipley and Marshall talked about it all in a video interview, as well as the fake controversy ginned up last year by champion ginner-upper TechCrunch–which, big surprise, runs a competing conference–about Demo’s longtime (and transparent) practice of charging a large fee to presenters.

“It was a false argument created as a marketing tool by a competitor,” said Shipley flatly.

What will be more pertinent and interesting in the Marshall era will be the integration between his VentureBeat Web site and the IDG-owned Demo conference, which could be a good way to take the conference and make it a year-round community of interest.

“We want to turn from a five-day affair into an ongoing conversation 365 days a year,” said Marshall, who also said the Demo model still works well. “It’s not that broken, so we will be tweaking it more than fixing it.”

Here’s the video of the pair chit-chatting about it all (sorry about the coffeeshop noise, but it was very festive):

Inevitably, in the wake of the collapse of the controversial Yahoo-Google search advertising deal, there would come the next shoe to drop–that Microsoft (MSFT) was swooping in with a bid to buy the company and that Yahoo CEO Jerry Yang was on his way out on a rail.

Maybe that should happen, but according to my many sources, a report in VentureBeat of this development is dead wrong.

And, said sources, Yang will keep his scheduled stage appearance at the Web 2.0 Summit today in San Francisco.

The culprits of the bad information? Surprise, surprise, those wishing to make some money on the stock market on the swirl of uncertainty around Yahoo. These stock manipulators have tried to spin BoomTown many times, and they are appalling.

More later, but the Yahoo (YHOO) train-wreck story, with its latest Google (GOOG) crash, is exciting enough without specious rumors.

Earlier today, BoomTown posted a video of star venture capitalist John Doerr’s 10 tips to start-ups for surviving the econalypse that he ticked off at a roundtable in Silicon Valley on Wednesday.

Beside the words of wisdom from the Kleiner Perkins Caufield & Byers partner, I also trolled for advice from the panel of well-known entrepreneurs I moderated at VentureBeat’s “How to manage your start-up in the downturn” event.

Thus, here is the i-will-survive take from Jason Calacanis of Mahalo, Toni Schneider, chief executive of Automattic, the company that makes the WordPress blogging software, Nirav Tolia of Web 1.0’s Epinions and Max Levchin of Slide.

As an added bonus, Ram Shriram, one of Google’s first investors, also weighs in. And, of course, the inevitable blogger Robert Scoble gives his two cents (and also freaks me out once again!).

Here’s the video of the entrepreneurs, and below it, for your viewing pleasure, two versions of “I Will Survive” by Gloria Gaynor (the classic) and Cake (the weirdly good one):

Here’s a video of star VC John Doerr reciting his 10 tips for start-ups to follow in the economic downturn.

Doerr gave out the advice at VentureBeat’s “How to manage your start-up in the downturn” roundtable event, which took place at the Stanford Park Hotel in Palo Alto yesterday morning.

The Kleiner Perkins Caufield & Byers VC got a lot of attention for his list, which he culled from a survey of 18 of the companies his firm has invested in.

Doerr didn’t need a massive, noisy PowerPoint like Sequoia Capital to make his quick and clear points, which he delivered in four minutes flat.

Doerr was on an investors panel with Ram Shriram, one of Google’s first investors, Ron Conway, Kittu Kolluri of New Enterprise Associates and Matt Cohler of Benchmark Capital.

I moderated the second panel of entrepreneurs, including: Toni Schneider, chief executive of Automattic, the company that makes the WordPress blogging software; Max Levchin of Slide, Jason Calacanis of Mahalo; and Nirav Tolia of Web 1.0’s Epinions. Video of interviews with them and also Shriram to come later today!

But here’s Doerr reciting his 10 tips:

It will take place at the Stanford Park Hotel in Palo Alto from 8 a.m. to noon.

Toni Schneider, chief executive of Automattic (the company that makes the WordPress blogging software) will join Max Levchin of Slide, Jason Calacanis of Mahalo, O’Melveny & Myers’ Sam Zucker, and Nirav Tolia of Web 1.0’s Epinions.

Along with my group, for whom I am planning all sorts of verbal tortures (”Exactly how much do you make?”), there is also a panel of investors, moderated by VentureBeat’s Matt Marshall, which features: John Doerr of Kleiner Perkins Caufield & Byers; Ram Shriram, one of Google’s first investors, Ron Conway, Kittu Kolluri of New Enterprise Associates and Matt Cohler of Benchmark Capital.

Oh, it is sure to be a festival of Web 2.0 pondering.

Said Marshall in a post about the gathering:

One goal of this event is to provide context and advice for start-up CEOs and founders facing the recession. We’ve handpicked the speakers for their remarkable records and experiences in the previous downturn. …

While the Sequoia [Capital] ‘RIP Good Times’ presentation gave a broad overview of the economic problems facing the tech world, it provided mostly a macro analysis, and a general prescription for companies.

Now is the time to take the analysis one step further, and discuss the variety of situations we see among valley investors and their start-ups: How cleantech companies are different from Internet start-ups, and how under certain conditions, a profitable company may actually be poised for aggressive growth, hiring and M&A–and not necessarily ideal for cost cutting. We intend to explore all of this and more.

Given the fairly predictable ‘Silicon Valley is in circle-the-wagons mode’ story line we’ve been seeing so far in the media, this event is also the Valley’s opportunity to help dispel this myth and explain how the area’s start-ups are actually quite diverse and that there are a mix of strategies at play.”

The event is sold out, but it will be streamed live.

And, as usual, look for a shaky video report of the roundtable from me later!

Earlier this afternoon, sources told BoomTown that Ben Ling (pictured here) was leaving his job at Facebook, a high-profile departure given that the social-networking company grabbed the well-known techie from Google (GOOG).

Ling and Facebook have since confirmed the departure to me.

At Facebook, Ling has been director of platform product marketing. He told his staff today of his plans to leave the company.

While some sources speculated that Ling was perhaps unhappy with the installation of uber-PR guru (and also ex-Googler) Elliot Schrage over Ling and others in the key platform arena recently, Ling was adamant that this was not the case.

Ling, in an interview today by phone, said: “I have huge respect for Elliot and work well with him.”

Ling would not be specific as to his reasons for leaving the hot social network, but he said he was pursuing “another opportunity.”

Mysterious!

He added that “Facebook is a tremendous organization, and I would not leave it if it were not for a great opportunity.”

Facebook has seen the departure of several key executives over the last few months, for a variety of reasons. Those who have gone include: VP of Product Management Matt Cohler, who is leaving soon to become a venture capitalist at Benchmark Capital, and former CTO Adam D’Angelo, who left in May to take time off.

Here is Facebook’s official statement on the Ling departure:

“Facebook confirms that Ben Ling will be leaving the company in the coming weeks to pursue other interests. We wish him well and appreciate his great contributions to the early success of Facebook Platform. Platform is poised for continued growth and success, and the company is on track to deliver the range of major initiatives announced last month at f8, including Facebook Connect, fbFund and the Great Apps and Application Verification programs. Each of these programs have a strong team of professionals focused on attracting the best developers to Facebook Platform, helping developers succeed on Platform, and helping users find and enjoy great applications on Facebook.”

The most excellent Eric Eldon of VentureBeat was also on the Ling-leaving trail and did a post that includes a lot of great reporting on Facebook’s platform too.

I have posted below a video interview with ContentNext’s founder Rafat Ali, who spoke about the deal. I caught up with him in his New York hotel this morning (by coincidence I flew into New York today on a redeye).

But the deal–which comes after the mid-May sale of Ars Technica to Condé Nast for a reported $25 million–begs the question of which tech blog might be next to be acquired.

And, after much noisy poking around today, BoomTown is giving the nod to one of the sector’s larger and splashier sites: TechCrunch.

Several sources told me TechCrunch has been in off-and-on talks recently with Time Warner’s AOL (TWX), which wants to pay from $20 and $30 million for the site.

I could not find out what price TechCrunch thinks is fair, although one might assume it is higher than that.

TechCrunch CEO Heather Harde told me via email that she had no comment. “My policy is not to comment on rumors of our business,” she wrote.

TechCrunch, which was founded in mid-2005 by Michael Arrington, is a group-edited blog that has grown large by focusing–”obsessively,” according to the site’s About page–on Web 2.0 start-ups, covering every jog and tittle of their life cycles.

Sources said the talks between TechCrunch and AOL have been ongoing for the past six to eight weeks, although the site has been in talks with several other large media companies interested in it in the past and these have not led to an acquisition.

AOL would probably be a good home for a site like TechCrunch, since it has a blog focus from its own Switched site and sites it bought, like Engadget.

AOL acquired that popular gadget site in 2005 in the $25 million acquisition of Weblogs, which was founded by entrepreneur Jason Calacanis.

Calacanis, by the way, runs an annual tech conference with TechCrunch, now called TechCrunch50.

Also, I have stayed in Calacanis’s house in the Brentwood (see post and video here), when I was interviewing a Disney exec onstage at a paidContent conference in Los Angeles recently.

Oh, yes, it’s a small tech blogging world after all.

But the money has suddenly become big for the sites involved in that universe too, although most still have relatively small businesses.

Nonetheless, tech bloggers have grown in number and influence, as sites–like this one–compete to break news and attract readers.

Such efforts take funding–despite the lower costs as compared with traditional media–and this probably means inevitable consolidation.

Before its acquisition by Guardian, for example, ContentNext had been raising several million dollars recently to fuel more expansion.

Other sites have also recently raised funds, such as GigaOm, Silicon Alley Insider and VentureBeat.

Most of them have also been talking about various roll-ups between and among one other. Sources told me that VentureBeat, for example, has spoken separately in the past to both paidContent and TechCrunch about joining forces.

VentureBeat’s Founder Matt Marshall would not comment on that, but did note that “size matters, so you have to do what you can to get the economics of scale.”

That includes adding on more sites and doing conferences, as VentureBeat has done (its new conference is called MobileBeat, for example, which will take place in Sunnyvale, Calif. on July 24.)

“Consolidation is what you are probably going to see,” predicted Marshall about the tech blogging arena.

Here’s ContentNext’s Ali talking about exactly that and more today:

Last night, dressed in my kindergarten soccer-coach best (sneaks, sweats and athletic socks–glam!), I ventured over to the Tenderloin district of San Francisco to attend VentureBeat’s party in honor of the launch of its new digital media blog.

Held at the Ambassador club on Geary Street, it was as if 1999 had never ended, and the huge crowd was partying like it was, well, 1999.

Shoulder to shoulder–or, in my puny case, shoulder to stomach–entrepreneurs, PR folks and a healthy smattering of press jammed into the venue, chattering about valuations, venture deals and other vacuous topics of Web 2.0.

Attendees included Mashable’s Pete Cashmore, Craigslist’s Jim Buckmaster, blogger Dan Gillmor and Microsoft-man-in-Silicon-Valley Dan’l Lewin (who gave us bupkis info about the deal, as you can see in the video).

Also in the video, in order, Meebo Co-Founder Seth Sternberg (fresh from a big funding); VentureBeat’s new editor of its digital media blog, Eric Eldon; Lewin; Gillmor; Valleywag’s Owen Thomas; and, finally, VentureBeat Editor and Founder Matt Marshall.

Well, I was kind of kidding at the end of a piece I wrote Friday about the possible top execs that Facebook might hire when I named Marc Andreessen at the end.

I mostly put the Netscape founder in there as a good comparison and to make a point about how Silicon Valley always has to elevate some techie to the status of Golden Geek of the Moment, declaring them the rulers of the digital sector.

Usually, their reign lasts as long as a potentate in some small and unstable country.

Nonetheless, in a piece related to BoomTown’s picks and also another post about Facebook’s actual search for a well-known Web exec to help lead the social-networking company, VentureBeat created a poll asking for reader input.

As you will see below, Andreessen did OK at 18% in the small sampling, while 21% wanted to let Facebook Founder and CEO Mark Zuckerberg just be Mark. “Somebody else” got 14%.

Most interesting result and the winner? Almost 50% thought a dose of new management did not matter, as “Facebook is doomed.”

An aPokealypse?
