Hot or Not is a service which works in a similar way to how Facebook was managed some time ago before being used by millions of people worldwide. You load up the app, sign in with either Facebook or your email and you're good to go. What you do from here is upload the "best" photos of yourself, connect with other people, rating them and becoming "hot". That's essentially Hot or Not in a nutshell, and now an official Windows Phone app is available on the store.
