That's really the vibe I got at ndindierock, although I know you are looking for the more mature musician set--nobody wants to work together, but they want everything to go their way. That might be the predominantly teenage music set there, but from what you say it sounds like the rest of the area musicians too.
It's interesting that you classify a message board as "action;" in most situations people would see a forum as the talk rather than the action, but I see what you're getting at. CD is the same way, in that we want to be a venue for action to be organized.
If I was a musician, I'd join in and get involved, but since I'm in grad school and have no real interest in playing in front of people anymore (even if I was decent), I don't think I could bring much to the conversation.
Have you tried getting a fix on what people (who aren't musicians or connected) want in the music scene? I think the problem in Grand Forks is that nobody really knows what the audience wants.
