This sight is definitely worth checking out. I believe it has been mentioned before by other members.
I took a clip from the FAQ page because I like it!

Franklin's polyamory FAQ
"So you're saying that everyone is either poly or cheating?
No. Some people seem wired for monogamy. They can stay in a monogamous relationship, and be happy, and never even look at another person. That's cool. "
I like this aproach to presenting poly because it is non-confrontational and does not look for flaws or boast. Great FAQ in my humble opinion
