MyYearbook, a social network for teens turned off by the old people thronging Facebook and MySpace, has raised an additional $13 million in venture capital. The social-network startup wooed by Barry Diller's IAC last year, but a deal never happened. The site claims to be the third biggest social network in the U.S.

Facebook's Mark Zuckerberg may be getting all the money and media attention lately, but News Corp.'s MySpace still dominates when it comes to traffic. The site commands more than 70 percent of visits to social networks, according to this latest chart from Hitwise. Still, its share declined 8 percent in the last year. Which might explain why News Corp. chairman Rupert Murdoch was rumored to be poking around runner-up social network Bebo recently. Oh, and by the looks of things, maybe Barry Diller should have acquired MyYearbook for IAC back when he reportedly expressed interest.

Yesterday, we floated a rumor that IAC was thinking about buying social network MyYearbook. Not the case, says Caroline McCarthy of News.com. Her sources hypothesize that MyYearbook's participation in a "mock pitch" session with IAC's Barry Diller at this week's Quadrangle conference was mistaken for something more than it was, a sort of moot court for entrepreneurs. We're not so sure. Our source told us that MyYearbook was "the winner" — and not just of that presentation. The site caught Diller's attention, possibly enough to set talks in motion. Were any potential talks nixed after word leaked to Valleywag? Quite possible. Diller likes to buy cheap, and rumors have been known to spark bidding wars. (Photo by saveena)
