I took a look at LJDrama, an anonymous blog collecting incidents of "drama" from LJ and similar sites. Basically, if someone blows their stack and goes off the deep end, their antics may well end up there. The thing is, most of this is teenagers with brightly-dyed hair and low self-esteem throwing hissy fits about who said what to whom and so on. The issues at hand all seem trivial and interchangeable; their exact details are seldom interesting or unique. To one brought up on a diet of kooks, crackpots and original thinkers, all this makes for rather bland fare. As far as genuine cranks go, LiveJournal has yet to produce an Archimedes Plutonium, an Alexander Abian, a Doctress Neutopia, or even a John "DrGodFuck" Grubor; the closest it gets to the lofty strata of psychoceramicity is a few kinky Furries and slash-fiction writers, and the odd joke community.
I wonder why this is so. Could it be that the social nature of LiveJournal selects against the original cranks and, instead, encourages crankdom to take annoying, lowest-common-denominator forms? Perhaps those who can be bothered setting up and maintaining a LiveJournal account are, by definition, too socially well adjusted to be truly eccentric or "out there" (and no, having lots of body piercings and being into kinky sex isn't "out there"). Perhaps true outsiderhood requires a degree of hermitlike isolation from others' opinions to truly allow one's mental reality to drift away from any sort of consensus.
