The image I have of the kind of person you're describing is this very niggling, petty, schoolmarmish people who are really devoted in a kind of sad way to their esoteric, arcane subjects and who are quite willing to defend, tooth and nail, utter minutiae. I'm picturing reference librarians, the less agreeable and more ornery sorts. Come to think of it, all this is sort of reminding me of academia and the kind of tempests-in-a-teapot that happen all the time all over the place in the academic world. Or so I'm told. Christ, who has the time? I actually read wikipedia entries a lot, and I like the concept, but I'll probably never contribute, just for the reasons you suggested, Sploops. I hear what you're saying loud and clear buddy.
