If facebook allowed alias accounts then I would be, but otherwise NO.
Having your "worlds collide" is just a complete disaster. Personally I'd have to maintain 3 accounts and I bet a lot of people would want at least two. I.e. Work and Play are SEPERATE THINGS. There are all kinds of bad combinations of friends, family, former lovers, people you would like to forget, work and buisness associates that I would NOT want to seat at the same dinner table and that's pretty much what Facebook does, frequently with disasterous social and political consequences. (Though the Failbook site makes GREAT reading...)
So Facebook is a sit back and anjoy the show from afar for me
