Actually, Hans Reiser was a heavy computer developer, not a computer user. I remember reading an article in Linux Journal in 2002 that more or less stated that Hans Reiser developed ReiserFS practically on his own. --I got the impression then that he was very focused on the development of ReiserFS, as he was doing nearly all of the work himself, without any real financial backing other than what came out of his own pocket. When I first heard about Aspergers a few years ago, I thought him to very likely have AS.
At the same time, it's sad to see what's happened, irregardless of his having Aspergers or not.
