I voted no, but I'm really more indifferent. It's not that I didn't enjoy the teams I was on at ACF - I did - but, on the other hand, if, like on ACF, they get to the point where they become like a mini-forum, I think it can mess with the general "unity" of the community because you get members that are completely withdrawn from the rest of the site (even sections like GC). It's true that on ACF it wasn't the teams that created the cliques, but they did reinforce them, since they were almost entirely self-sufficient.
