On average I'd rate him a pretty good interviewer however it seems like the quality has declined recently. E.g., his interview with Michael Malice a few weeks ago, where he (Lex) confessed to pulling an all-nighter before the interview, and so wasn't on his game. It showed. Hopefully the lesson he took from that experience is he shouldn't pull all-nighters before an interview.

As the commenter above said, lots of 'meaning of life' questions that just aren't that interesting.
