Where do you stop though? Do you end up with 27 different forums all containing a few threads each, or do you keep them all in the one place? As per the way PH does it, I don't bother reading 3/4 of the OT forums there as they don't interest me as a rule, however on the odd occasion I browse them there's the odd thread or two worth clicking. Still not enough to make me read that section every time, though.
Personally I like the OT section here as it is, it's nice and varied and you never quite know what you're going to get.
