This is a fantastic piece of work. The user journey seems pretty seamless. Using the googls or FB auth is a pretty sweet addition as many people use one or the other of these services. It will be a great marketing tool for hive as users become more exposed to the platform as they traverse "traditional" web and social channels.

I really like the idea of a "stored reward" section. It would be really neat to interact with the non hive user to let them know that they have X hive waiting for them on signup. I don't think I saw anything in the post about it.

All in all nice work!
