WEB 2.0 SUMMIT — Special correspondent Paul Boutin is reporting by text message, which is fitting, since apparently this morning's keynotes from Microsoft's Steve Ballmer and eBay's Meg Whitman can easily be condensed into a Twitter. Or less. Conference organizer Tim O'Reilly, in fact, has all the good lines. O'Reilly to Whitman: "You become what you disrupt." He means, Boutin texts, that eBay is now the old guard waiting to be Napstered. That's also evident in a following exchange, where O'Reilly points out that you can't Skype people by clicking from a Facebook page or using an email address. Whitman's only response is that it's easy to look up people in Skype's directory. Meg, it's time you had a chat with Mark.
