A new app called Stamped aims to simplify the whole rating process (and business) by making you and your friends — the only people who really matter when it comes to ratings — the creators of your own very personalized rating directory.

And with a limited amount of “Stamps” to dish out in an allotted amount of time, you can be sure that your personal “map” won’t fill up with Stamped spam from friends using the service.

Sounds intriguing, but the hardest thing is getting your friends aboard with you, so send them over to this link! It’s a free app.
