> Require FB auth.

This is an instant dealbreaker for me nowadays. I refuse to have a Facebook account for a number of reasons and know a couple of other people that are the same.

However, requiring FB auth may not make a large impact on the number of users registering for the service and/or users like me may not actually be within the range of users who would be interested in the service.

(Personally, I think it's a really nice idea. A bit of positive feedback can go a long way on some rough days.)

I'm actually more curious about how the site could handle multiple people with the same names, or users who don't really think about it and just put in "John" for the name.
