Dave McClure comes off pretty poorly in my opinion, everyone else came off very intelligent with excellent points.
EDIT: To back up my point about Dave, he focuses completely on building profits. Its easy to say "Hey Apple makes 7cents on the dollar" but it shows a lack of foresight.
I believe pg commented that we're all slaves to Steve Jobs and Dave McClure remarked that 70 cents on the dollar is not a bad wage for slavery. His point was that you can hardly call it slavery when your cut of the profits is significantly bigger than your master's.
