Tent is a decentralized social network:
Tent is a protocol for open, decentralized social networking. Tent users share content with apps and each other. Anyone can run a Tent server, or write an app or alternative server implementation that uses the Tent protocol. Users can take their content and relationships with them when they change or move servers. Tent supports extensible data types so developers can create new kinds of interaction.
Tent is for sharing with others and seeing what others have shared with you. You can ask to follow other users and other users can follow you.
Incredibly exciting. If nothing else, I’m glad to see people experimenting with social networks and not ceding it all to Twitter and Facebook.
