I made a FB account for my steampunk character Lydia Bailey? Pretty much everyone in the steampunk group from Otakon has one, and I've received a number of messages asking me to friend people.
I am partially considering it to make things a little easier organizing events and such.
But then again, Facebook, ugh.....
It'd be strictly for cosplay things though, so perhaps I wouldn't be a TOTAL hypocrite.
