I would have thought that a Facebook login would lead to less spam (since most accounts are real people rather than an anonymous person hiding behind an anonymous email address).
I'd like to hear other people's experiences onto how good a Facebook login is. It's a chore to sign up to a website (fill in form, wait for email, click on email link etc.) most of the time, it would be interesting to hear how a Facebook login can actually increase site activity.
