This afternoon, I'm hopping in my truck and driving down to Philly, where the Annenberg School for Communication is hosting a conference on hyperlinking. I'm on the first panel of the morning, with Jay Rosen, Tony Gentile, Eric Picard and Nancy Tellem. Should be a fun time. Maybe I'll get to meet David Weinberger. First, though, I'm doing the ad:tech radio podcast with Susan Bratton, which should prove to be fun and interesting.
