I would've loved to try it and I don't mind the Connect with Facebook option like some folks do (I prefer it). But I didn't try it because it said that you required access to my email address. No thanks. My email isn't hidden or special (it's in my profile, for example) but I have a real problem with giving it up in exchange for registration without a clear reason ("We need your email to do x, y, and z") and without a clear sense of whether you're going to sell my info.
