Just got a ping from Jim with the official Web 2.0 Expo twitter account. Go to http://twitter.com/w2e and add them as a friend (I have already). It looks like they are adding most folks as friends so we should get a cool stream of info like at SXSW (which I followed via Twitter).
They say the tweets from friends will be on the lobby LCD screens … looks like it’s going to be wild. Watch your cell phone bills folks, there’s gonna be a lot of twittering soon!
