To be honest he wasn't the only one asking stupid/long-winded/time-wasting questions. Some people kinda need to learn how to prepare and succinctly make a point.
a) The people asking questions weren't public speakers. Speaking in front of 800+ strangers with a mic in your hand is nerve wracking for a lot of people; cut them some slack.
b) Nobody else had such a huge ego to interrupt a speaker on stage in the middle of his talk. Let alone in the first 5 minutes of it. It was humorous that he interrupted the CEO of Zappos to ask a question about how to figure out who the ego-centric people were.
