Yeah, that guy seems to be a jerk for sure, Chuck. But there's one (or more) in every crowd. I wouldn't let that keep you from posting over there - just ignore him.
For the time being, I'm covering the gamut until I see what shakes out. I've been a member of JazzCorner for a long time - they are re-designing over there and will have a re-launch soon. Also, I will keep an eye on 'harlem.org' (still sleepy even with the new members), AAJ and here.
I plan to keep checking in to the BN site, too. I think it still might be a good source for discussing BN topics. We'll just have to see what they do with it over the next few weeks. It's a mess right now.
