what the hell, here's some lame ideas:
/haiku/ - general discussion, but all posts must be in haiku form
/quack/ - post about your personal issues, and be internet diagnosed by strangers with a fleeting knowledge of pop psychology and access to webmd.
/bowl/ - for posting pictures of your most recent bowel movement, for other users to try and guess your diet.
/ban/ - this board has 99 rules, the first 98 of which are 'don't post here'. Any user who creates a post here receives a site-wide permaban.
