Keranu linked me to this thread for good reason I guess. If there was ever a question right up my alley, this is it.
Snow Crash is not not for you if you want serious cyberpunk. In many ways it is a parody of the genre, and in my opinion, it is the nail in the coffin that killed the genre, showing how retardedly obsolete the genre had become. It is a great read if you are looking for something funny, and I would recommend it for the first chapter alone.
If you want some more serious Stevenson stuff, try Cryptomicron. It's good post-cyberpunk fiction involving two guys trying to set up a data haven, searching for Japanese war gold, and World War II cryptbreaking. I don't think your ADD could take reading the whole book though, it is really long. Snow Crash really does fit your hyperactive posting style, Kitsune, so try that.
