I feel the same as london. I know it sucks that FB is so poly-unfriendly, but I don't get why FB relationship status is such a big deal. If you want people to know you have more than one partner, you have other ways to tell them. If your only contact with someone is via FB, I doubt it's important for them to know your relationship status anyway.
