I've now read three Chuck Palahniuk books, and I have to agree with Bill, he's not nearly as shocking as he thinks he is. His books are interesting, and I guess I sort of enjoyed Fight Club (although I already knew the twist, as I have been on the internet in the last 10 years), but I certainly didn't love it, and probably won't read it again.
Maybe it is just that violent hypermasculinity doesn't appeal to me. Or the idea that that's what all men are secretly waiting for because they lack father figures. If you don't buy the philosophical underpinnings, it's hard to get on board.
It does seem to sell men rather short, though.
