I thought the reason why people left the SXSW interview was because the interviewer was a giant, self-absorbed douche who gave Ev little time to speak and/or didn't do a good job of facilitating.
Interviwer: Ev, I've read that Twitter is being used by dissidents abroad to drum up support for their causes and bring them together, giving us yet another example of social media being used for guerilla political purposes. Is this true?
Ev: I think so.
And on and on and on...
