This is really nice and clean. Personally, I think it's a bad name though. Minus? I appreciate it does "emphasize simplicity and minimalism", but it's got nothing at all to do with images. Also, it would be even better if you could include some form of federated login so I don't have to sign up.

This is Carl, cofounder of Minus. Thank you for the suggestions. We are looking into adding OpenID and Google Login soon. In the mean time, we designed Minus in the hope that you can use Minus effectively without having to sign up at all!
