I like the concept. I don't really want to login with Facebook [1] to understand the mechanics and see if it is something I might want to use. That outweighs my interest in providing more detailed feedback on the project.
From a user experience perspective, a question to consider is "Do users enjoy logging in?" If the answer is 'no' consider making logging in optional (opt-in) and making the product better until people are opting-in or making the product better by creating features that don't require logging in. Either strategy reduces friction when potential users want to learn more about the project.
Good luck.
[1]: Actually I don't want to login at all. And over the long term, I don't want to log in with anything more cumbersome than Hacker News.
