Conferences are like onions, .. and ogres – they have layers: your coworkers, your former coworkers, speakers, vendors, competitors… relations. The best way to see the various layers is through twitter, or Xiive.
Tagging the tweets #gotoaar makes it possible for others preparing for the conference to look into – what are people looking forward to, who is stranded/delayed. People in the tracks and at the keynote typed what they wanted to say, but couldn’t in the forum. Some did a rapid blogging summary of the track session and provided the link to the blog on twitter. It was like a “Back channel” to the session, you could be in one track and follow the “gold nuggets” – and occasional outcry – of the others.
First thing is to see the layers – the next thing to do is to network.
