&gt; I don&#x27;t want to drag in a social graph along with identity auth, but YMMV.<p>As I read it, that&#x27;s completely optional, and I think since that doesn&#x27;t exist yet (right?), having that option sounds great. I&#x27;m probably naive to dream of diaspora etc. and Facebook getting along, but even just smaller sites playing nice could make this very useful.
