Ableson vs. Sussman

Why does /prog/ love Sussman so much but never talk about Ableson? He's not very charismatic but neither is Sussman. They're both extremely geeky, but Ableson strikes me as a brilliant autist while Sussman comes across like one of those nerds who thinks they're smart because they've mastered Dungeons and Dragons and Star Wars trivia.

Your thoughts?
