If I had to label myself, it'd be a .org'r ... but I have frequented the zone quite a bit over the years. I also visit several other music related message boards & let me tell you, PZ definitely is not the "leader" of negativity & such ... IMO, that award EASILY goes to the "green board" (phish) on phantasytour.com. Some of the other colored boards on pt are not far behind. You need a thick skin or at least a good compass.
On the other hand of the spectrum, I have found the Telluride Bluegrass Festival forum www.festivarian.com/index.php/board,4.0.html to be almost spooky how friendly & cordial the tone is over there!
All it really takes is one individual to take down a board ... I've witnessed at least a few times. Add in a few bad apples and appearances can be deceiving ... as if there are greater numbers of bad apples than there really are.
