I attended BarCamp Day One (Friday night) -- very cool. Too bad Marc Canter wasn't there as it was about as unconference as it gets; he would have loved it. The interests were quite varied - everything from Web 2.0 to "Old Macs".
I met several entreprenuers who are completely bootstrapping their startups with open source and teams that are remote (i.e. working from their houses). Some people seem a bit squeamish about admitting this, until I tell them that MessageCast (and Bloglines) did the same thing. We didn't move into our office in Redwood City until we had been at it for more than 2 years. The new paradigm - embrace it.
