I understand why they want Zuck to speak (it helps raise the profile of the event) but I'm not particularly excited. His talks are notoriously stodgy and unfocused, especially his Startup School appearances.

I'm much more excited about Max Levchin and Drew Houston. From past talks I've seen them do, I feel their message will be better focused and higher yield for the startup audience. The best talks last year were from entrepreneurs who had tasted a mix of failure and success - Dalton Caldwell and Brian Chesky.
