Maybe it shows that people are just stupid and lots of people join these forums so some are bound to be stupid and many have proven to be and so they take the general stupidocity of the forums up and so everybody else becomes slightly stupider by being in their presence and the actual board becomes stupider, even though it never showed any signs of a personality, and it starts showing stupid adds which means that other people see the adds and, because they've already become stupid, they take too much of the adds in and become even stupider again.

Or... vampires are neato!
