Jon, regarding your first paragraph, it's not the forum that causes those things to happen, it's the emotions and reactions of the people posting. If the forum were split up, people would still do all of those things. Trolls and overly sensitive people would still way-lay threads to be about the method of discussion and their personal feelings instead of the subject. A music-only discussion could wind up being "this song is ___ist" or "are you calling me an idiot because I posted something already in the DT." Easily offended or frustrated people would still get pissed off and leave. It ain't the forum that's broke, it's the way some people start crap and others, who should know better, encourage it.
