Chan Boards

Chan boards like 4chan and 7chan are image posting/message boards that tend to have a lot of porn and nerdy stuff including anime and various other things that aren't very popular in the mainstream.
What sets them apart from other types of boards is their expectation of anonymity (all posts are anonymous by default) and there specific culture which seems to be constant across many of the different chan style boards.

4chan is the most popular and 7chan seems to me to be next in line.

It all started in Japan with 2channel which at one point almost shut down and so in case it had shut down, Futaba Channel was created. Internet users not in Japan are not able to post on these and thus 4chan was created, which it's self spawned many other English imitations.

The Overchan is a directory of 2channel/Futaba channel style image/messageboards. Most of the boards listed are English but a few are for other languages.
