The Three Stooges of Silicon Valley found a Shemp. After Michael Arrington spoke at Dave Winer's BloggerCon, the TechCrunch blogger got sucked into Winer's little club — Winer, Marc Canter, and Steve Gillmor.

As long as you're pretending you went to Supernova, pretend you hit every conference in downtown San Francisco this week. Old-school blogger Dave Winer is holding his BloggerCon "unconference" down the road from Supernova, and he can only let 150 attendees in at a time. (At least at Supernova, there's room to sneak into the Palace Hotel and schmooze for free.) Don't worry, Dave and his attendees are making BloggerCon the most un-unmissable conference of the season.

Hoo boy, four San Francisco conferences in one week! Starting with today's MashPit, this week is a con junkie's dream, as long as you have a guide to getting through.
