Perhaps to clarify, I think people in your area that are making "weird" music should be encouraged, invited to shows, and included in what's going on... I'm certainly not advocating isolation or holding oneself aloof from anything that isn't harsh noise / PE. I think a variety of "experimental" music is great, and I'd rather have that variety - a nice avant-garde percussionist one week, slamming heavy electronics the next, a bill with a mix of drone and harsh noise after that...
I was more-so speaking about the people that show up to tinker with their gear if they get put on a show, and otherwise show no interest in touring artists, or even noise music in general. I think it's really valuable to try and build up a local experimental music community, but if people show no interest in that beyond their own tinkering (they're not interested in touring acts, they're not interested in good music that is coming out of the genre, they aren't listening to the classics) then I'm less interested in what they're doing. And it usually shows in their musical output - these are the projects that tend to stagnate in mediocrity, opening for a touring artist they've never heard of 4 times a year with the same boring performance.
Basically I'm not advocating isolation or elitism, I just think people should be encouraged to be excellent. Good noise artists in the same area tend to mutually reinforce each-other's output, you see that over and over again.
