I have read alot of Larry Niven. I liked Asimov too. Couldn,t get into Jerry,s stuff much.
I don't know his work, and due to his gratuitous bashing of things in his "Chaos Manor" monthly column (hmm, that was in one of the computer magazines, remember those? ;^) including one really dumb one regarding modem data formats (remember those? ;^) for his communication with his then-publisher, I wasn't inclined to read a book's worth of him until Lucifer's Hammer. Probably worth reading his collabs with Niven, but I just don't read fiction. :^)
