Twitter accounts from Web 2.0 Expo in San Francisco are really diverse, as the conference kicked off earlier today.
It isn't Pubcon, SMX (SMX Social coincided the first day in Long Beach), or SES. Definitely not SXSW :)
It's a little of each ... plus a lot of popular bloggers, many of them new to the conference scene.
