Thiel is an interesting that character I would like to know better, but he is not the best speaker. I wonder how comes is he so successful despite not looking very convincing, neither dominative or confident person. When the (boring) interviewer asked about the Gawker sex tape, he was literally sweating and looking for water with his shaking hands. Other answers were kind of dull, it's difficult to understand his ideas.
