My only problem with this idea is that one of the reasons those threads exist is to just post random crap you're having fun with and move on, since most people don't really care to discuss anything but a few subjects here and there.
If we had, for example, an entire subforum dedicated to gaming, we'd have dozens of single-game/series-related threads that get no responses and then a few threads that get insane amounts of responses just because the game is more popular. I mean maybe if we had threads dedicated to separate companies they'd be more active but it would still sort of divide up the gamers of the forum, and that wouldn't be nearly as fun as the gaming thread if you ask me. Even if many people don't discuss every little thing posted in the stickies it still gives a nice community feeling to them.
... And that's just Gaming... Think of how chaotic the Music "subforum" would be.
I do support Troll's idea of a subforum for thread games, though. Even though General Discussion would likely become a lot less active, haha.
I could see an Entertainment subforum being a good idea for threads that don't really fall into the big three as long as those can stay stickied. I wouldn't want the stickies to be dissolved and replaced by a slew of response-less threads. :C
Now what might this be?
