The Web 2.0 Summit took place this past week in San Francisco. While I participated in a few AOL sponsorship events, I also participated in Lobbycon. In my short time at the Summit, it appeared the Web 2.0 Summit seemed to be more of a "suit" fest while the Web 2.0 Expo, this past April, seemed to be much more approachable. Nonetheless, Facebook was all the buzz and Mark Zuckerberg spoke with John Battelle at the conference similar to how Mark Zuckerberg spoke with Mike Arrington a few weeks ago at TechCrunch40.
