Sounds cool. It may be an idea to have an individual button in each section (I mean broadly - chatter, interests, utility etc), just to ensure you don't end up with a thread in the wayside or the TB if you didn't want to. Then again, I suppose it could just be restricted to choosing a random, non-erogenous zone thread, which would hopefully get a few more people interested in the more (or possibly less, in the case of nonsense!) sensible parts of TFP...
