Thing is, forums like this sit in the hazy area between 'random' forums, like SA etc, and 'official' forums, we represent a single game, and we do so fervently, but are also, for the main part, moderately relaxed about the general discussion forums, you'd never see the kind of discussions allowed in GD appearing on the Sims 2 forum, for example. So, in general, I think we try to keep an air of 'decorum' without trying to control the flow of discussions too much.
Edit: In fact, one of the things I love about this place is the level of discussions that can, on occasion, take place because of that relaxed attitude.
