+        Decentralized, federated video hosting network. Still quite small, but is growing and has a dedicated community. Although there is no central database/server, all the separate instances can still talk to one another. This allows for data exchange and a way to view anyone's videos while only associating with one instance. Thanks @kdkasad for clarifying federation.
