Well, I'd like to leave, primarily because I don't trust facebook with my personal information, or at least I want to be in control of how it's used. But I often find sending messages with facebook more pleasant than sending them via my email account for some largely aesthetic reasons. And I really enjoy being a little closer to (knowing about, basically - photos, status updates, etc) my geographically distant friends and email does not permit that at the moment. I'd definitely leave for an open, easy-to-use system where I am in control of my personal data's usage. Perhaps an open protocol that email providers could abide by. But until that day I'm sure I'll stay, albeit while attempting to minimise the personal data I exude (which is difficult, I know).
