I like what we have going right now. It's probably safe to say that most of us, aside from a dedicated bunch, don't care to see the Halo or WoW threads on the front page at all times. Those that regularly participate in the threads aren't effected, and it removes a bit of clutter for the rest of us. If anything, the Community forum encourages tight-knit, "exclusive" communities (that tend to talk about more than just the game/topic) so it makes sense to tuck them away since the average lurker or poster won't ever take part in the thread.
But with most OT's, I'd prefer to keep them in Gaming since part of GAF's appeal is it's lack of dedicated forums for everything. It keeps discussion active at all times, you'll never log into GAF and see stale threads on the front page. I keeps my two tabs open and I'm set.
