The Lobby, David Hornik's Hawaii funconference, may have no agenda — but a lot is happening all the same. One delicious incident recounted to us: TechCrunch editor Michael Arrington, who'd previously wooed BusinessWeek columnist and Valley fox Sarah Lacy onto his TechCrunch40 judges panel, apparently said something that made her throw a drink in his face. That's the first thing I've heard about The Lobby so far that actually made me wish I was there. Update: We hear the glass was empty. Okay, so make that two wishes: That we were there, and that Lacy wasn't so quick to sling back her booze.
