This map of the various species of geek--and their activities, obsessions, slang, idols, and social communities--is stunningly exhaustive. Not much to say about it, except that there is perhaps one type of geek missing: The Infogeek. That is, the kind of geek that would spend weeks on end tabulating such a map, color-coding it, and drawing it out. Full-size version here [2].
