True, but for most folks logging in with another service (FB, Twitter etc) is the same as 'no registration'. Clearly, it's also where they get the data about you to use the service at all. Seems they need FB connect and 'additional permissions' [1].
It'll be interesting to see if they decide to add further methods of logging in (twitter/linkedin) but I wouldn't be surprised if this remains FB-only (I've decided I won't be trying it out since it's FB only).
