He's so frustrating to me as a libertarian. He sometimes says things I agree with so I want to believe he's not a complete lunatic but then he wears those glasses and starts writing on a chalkboard...
He did a show on one of my favorite books (The Road to Serfdom) and got people buying it which I think is a good thing.
I've only seen his show from clips on the Daily Show though. I have no interest in wasting my life watching his show.
