Matt Taibbi acts like a jerk

I saw my hero, Matt Taibbi, on Bill Maher's HBO show tonight. His writing is scorching and so intelligent, but in person he comes across as a cynical ass. He even commented on Hillary Clinton's necklace (apparently it looked like a snake). He seemed immature and bratty instead of informed and insightful. Really disappointing, but I'll still read what he writes, as that's clearly his better medium.
