This little blog just got rolling, but I find the concept pretty hilarious. It is basically a blog about how to post on message boards. It discusses fads, Internet lingo, popular message board videos and pics, and even gets into ways of how to survive on a message board. I expect this blog to become one of my regular reads in the future.
If you find the psychology of message boards and the way people tend to display their superiority over other posters funny, take a look at Internet. Serious Business. for some tips, and a few laughs.
