Most the new people that start out here, myself included, join because they are having difficulty coping with something they've been taught all their life is immoral. Others are posting about their insecurities and seeking guidance of getting past that. People don't join forums to profess how easy life is. That's both boring to read and to talk about. Not everyone who posts here is interested in being poly either. There are mono people who join to get help or perspective about their significant other, people who have been asked to consider poly, and all sorts of stuff.
If you think this is a swingers board you should go look at swingersboard.com. I was actually told by people there to not even attempt to include emotions because that is disaster. So no, this isn't just some swingers board masquerading as polyamory. This is a place where like minded people can talk about their issues.
