I hate to derail this topic to talk about 4chan, but I think that 4chan is many-faceted (and, indeed, the level of anonymity has varied across time and from board to board on the website) so I'm not certain an informed opinion could ever be COMPLETELY informed. Certainly, somebody lurking on /b/ for a few months might have something to say, but they're missing out on the sub-boards, which have their own board cultures and memes in microcosm. Again, moot goes to 4chan a lot, so I'm waiting to see what he has to say.
