I think Douglas Adams, maybe, for his quality to bullshit ratio (arguably 6:1, cause Mostly Harmless definitely wasn't very good). Because of my love for him I got into Terry Pratchett, who's ratio is nowhere near as good. I'm also partial to Stephen King, if only because The Gunslinger is my favorite book, as well as Frank Herbert (Dune), Isaac Asimov (Foundation in particular, nearly everything else in general), Dan Abnett (he turned me into a Warhammer 40000 geek, the bastard), and David Sim (who created Cerebus and blew my mind several times but kinda lost it in the 90's and never came back). Let me throw HP Lovecraft and Robert E Howard (creator of Conan the Barbarian) in for good measure.
