Another forum at which I used to post, like five years ago, had these Random Thoughts threads.
They'd get up to like 1,000 posts, and then we'd make a new one. We were up to like Random Thoughts 20 or some shit. I never did understand why they'd close it only to make a new one. Does that help with bandwidth or something?
EDIT
Now at another forum at which I post, made up of a lot of the people from the other forum, we just have "(Insert month) Randomness".
