Podcast Philly and Search Philly
The reason why I insist on attending as many podcamps as possible is because I always learn something. I also get to share of myself. The most valuable part, though, is discovering what people do and don't know and do and don't care about -- we all tend to be so in the bubble that we don't even really know any more where the market is. Since we're in the advance guard, many of us assume that Twitter, Second Life, Facebook, MySpace, blogging, and everything are already over in a time when people are just, still, in discovery mode. I can highly recommend attending. And, even more, they're generally either free or about $40.
