Socialee has now been released with compatibility for EE2.2.
As before, it supports social sign-in through any of 20+ networks and authentication providers, sharing widget to post simultaneously to Twitter, FB and more, and social analytics to track your sign-ins and sharing through Janrain.
(note that many of these features require a $10/month Plus account from Janrain.com)
