Have to agree that starting a thread with something that's bound to get some people angry is just plain mischievous. Lately we've had things like "Why are Americans......? They're just insults in the guise of discussion. I see nothing wrong with starting a thread on a social issue (or a humourous one) but if the person doesn't have the intention or the imagination to be nice.....screw 'em.
Sometimes it's frustrating to start a thread on a music issue and see so few people interested in it, and like Michael K, I'll often take a look at some other threads and see the same folks again and again again. But it goes "in and out" and "up and down" doesn't it?
Let's face it, Mudcat is part chat, part therapy, part boredom reliever, and part information site. On occasion I've noticed that someone has a really serious issue (not related to music) and it brings EVERYONE in. Just don't make it the ONLY thing in your life!
