... seems to attract some of the most vapid, self-righteous "drummers" ever assembled anywhere
Mike, respectful people often get accused of being self-righteous. It's nothing new.
...and the micro-moderators seem hell-bent on stifling any real debate.
By real debate, do you mean when it gets nasty? Because yes, that's when we would step in. Otherwise, you can debate all you want there.
The members of DrumChat often comment that what they like the best about the forum is that everyone is so nice and there is rarely any drama. But if you see that as vapid than that's Ok. There's always DrummerWorld right? So no harm is done. We all have different tastes. There's a forum for everybody out there.
