The team behind the Pinwall BlackBerry social network just released a new app/service called Pinvote. The app lets you rate the attractiveness of pictures submitted by other users. Its as simple as that.
The only real twist is that you can buy credits which let you contact the person you rated on Pinvote. I am not sure exactly how that would play out but it sounds kind of creepy. Still if you are into this kind of thing check it out from your PC or download the app to your BlackBerry at www.pinvote.com.
