I just scanned over the last ten days posts in each forum, and other than in sports, there just isn't any unique activity that would not be replicated here or elsewhere if that forum ceased to exist.
The fact that there is an active sports forum there is a mystery, because I would think that the same subjects discussed there could be presented to larger audiences elsewhere. Don't ask me where, as I'm not an internet junkie, but I would think that there must be sports forums with hundreds of thousands of contributors, just because every city in the northeast has call in shows with hundreds of daily callers who, if they can read and write, could post ideas similar in depth and perspicacity to... oh, never mind!
