Think you take the best selfies? Prove it. Facefeed is a social network for selfie-aficionados with a popularity ranking system. Set up a basic profile, select a user from the main screen, then send a picture to connect. The caveat is that you can't see your snapshot before you share it -- once you release your finger from the shutter button, the image is taken and you can't edit it. Add a message with your picture, and if your recipient likes your selfie, he or she can choose to friend you. You can also add anyone you've messaged as a friend, and the higher your number of friends, the better your ranking.
