Done? Okay, not have a look at Wikipedia's entry on Elephants:
Because of recent vandalism or other disruption, editing of this article by anonymous or newly registered users is disabled (see semi-protection policy). Such users may discuss changes, request unprotection, or create an account.I am both amazed by the ability of public figures to incite something like this and Wikipedia's ability to resist it.
EDIT: Oh, when you're done seeing those two things, read this.
