I have read a lot of Vonnegut. He was also big among college students in the 70's. There is currently a renewed interest in him, I think largely because he not only had a unique perspective on Man's place in the general scheme, but also because he was able to hit the nail on the head, so to speak, in the way that he communicated his view. Fortunately (or unfortunately, as things stand in the world today) his themes continue to be relevant.
