Show HN: icare - Open Source carpooling application built with RoR and MongoDB

Hi, we are using Facebook at the moment because icare is in a demo state and Facebook provides personal information that is important for a ride sharing project. Unfortunately twitter doesn't provide us e-mail address and people do not use their real name: we think we need our own authentication system to allow pepole linking their own twitter account. Google+ is an option we are considering. It's not just a matter of API because we are caching facebook likes and friends with their ids to highlight common interests.

Hi, thanks.

This is not relevant for us but they can be very relevant for your potential travel mate. We are explaining it in the "Why Facebook" modal.

Any feedback to improve this aspect is welcome!
