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.

BoomTown managed to sneak into the green room at the Web 2.0 Summit last night to get a little chit-chat in with Lance Armstrong, the seven-time winner of the Tour de France cycling race title.

Armstrong is now probably going for his eighth one, much to the chagrin of France (yes, the whole country, as Armstrong notes in one of the clips in the video below), part of his “comeback” from a three-year retirement.

Here’s a video of him talking to me about his health and fitness Web site, Livestrong.com, and some snippets from his onstage interview with Web 2.0′s John Battelle, along with some crazy bidding for a bicycle he signed:

On Wednesday, an always worthwhile Internet-focused conference, the annual Web 2.0 Summit, kicks off in San Francisco.

The lineup for the three-day event is particularly good this year and it is also a perfect time to take the temperature of the Internet’s movers and shakers, given all the hubbub of late with the weak economy. (BoomTown will thus be there with the trusty–and shaky–Flip video, chronicling it all for future generations.)

Speakers will include bicycle champ Lance Armstrong, Yahoo (YHOO) CEO Jerry Yang, former VP Al Gore, Google.org head Larry Brilliant, Paul Otellini of Intel (INTC) and Facebook’s Mark Zuckerberg, among others, chattering away on a wide range of topics. (You can see the full schedule here.)

There’s also, of course, a passel of parties, including one on Thursday night thrown by MySpace Music. And it will–shades of Web 1.0!–feature an exclusive performance by Lionel Richie (and also DJ AM).

I am, I shall admit it and without irony, a closet fan of Richie. And why not, with so much infectious fluff to choose: “Hello,” “Say You, Say Me,” “Three Times a Lady.”

Most importantly, I will be curious to see if there will be “Dancing on the Ceiling” among the beaten-down start-up crowd. (See that music video below and ponder exactly why you know you know each and every word to that funkadelic song.)

Hosted by Tim O’Reilly and John Battelle, the Web 2.0 Summit is called “Web Mets World” this year. By that, BoomTown is inferring that its organizers think it is time for the Internet to grow up. But why don’t we let them speak:

The commercial web is now a teenager—it’s been fifteen short years since Marc Andreessen released the Mosaic browser. To put this in perspective, television as a commercial medium reached its fifteenth birthday in 1956—the year Elvis Presley made his first appearance on national TV…as we pondered the theme for this year, one clear signal has emerged: our conversation is no longer just about the Web. Now is the time to ask how the Web—its technologies, its values, and its culture—might be tapped to address the world’s most pressing limits. Or put another way—and in the true spirit of the Internet entrepreneur—its most pressing opportunities.”

And, of course, here’s Lionel:
