I am America (and so can you)

Far from it. I don't think it's much hyperbole to say that Colbert is a "comedic genius." Both he and Stewart do a great job summarizing and satirizing daily events. Personally, I think Colbert has exceeded Stewart. You don't have to agree with them to recognize their talents. What's especially refreshing and revealing is to hear actual interviews with him. He had a great one explaining the difference between him and Stewart. I'll look for it later.

All that said, I've always felt I'd be very disappointed by their books so I've never read them

Has anyone ever seen Colbert's roast of Chevy Chase? Brilliant

I'd agree with that.
