Cryptopurr is a 'Facebook for Cryptokitties' or any ERC721 token built on Ethereum by Userfeeds.io. No fees, open data layer. You can purr on test networks, so it's 'for free' (check your Kovan address - there should be a little gift if you have kittie).
The vision was awesome (Medium post), sharing an actual (open source) implementation is even better - kudos!Cons:
A code experiment for a fascinating vision. The idea of using NFT as avatars is congruent with the trend towards decentralized identity schemes.phil_h has never used this product.
