So, I finally came out on Facebook.
This is after having finally come out to my aunt and uncle, indirectly, by coming out to my cousin, who was then able to tell them. They're supportive. Only person who doesn't know, now, is my grandmother, and she's not on facebook.
I set my relationship status as 'in a relationship', unnamed, a couple months ago, to good response. Now, I set my status as 'in a relationship' with a guy, and set my 'interested in' as male (well specifically, I'd had it as that before, but only viewable by me. This time I set it publically-viewable.)
