The community itself looks pointless, but what amuses me is the default icon. http://www.livejournal.com/userinfo.bml?user=_wtf__
The icon says "HIGHLIGHTING THIS ICON WILL MAKE YOU LOOK EXTREMELY STUPID". I highlighted it in Firefox, but saw nothing unusual; Firefox highlights images by putting a uniform blue tinge across them.
In Internet Explorer, though, something interesting happens: IE highlights images by blacking out every other pixel in a fine checkerboard pattern. When that happens, the words "YOU FELL FOR THAT? DUMB CUNT."
The concealment method is as clever as the insult isn't. :}
