What does it matter if a few people didn't understand him? (I understood him just fine; I thought the interviewer was terrible in the questions he asked, especially the initial one.)
I don't have strong opinions of the interview one way or another. I don't think he did well, but I understand that he was probably way out of his element. However, anyone getting on TV to talk about anything related to bitcoin better have general answers ready for questions like these. A generic question about bitcoin when he is expected to talk about MtGox should not completely fluster him.
