Description
Mastodon is a free and open-source social network platform built around micro-blogging. Unlike centralized services, it works as a federation of independently run servers (called instances) that communicate with each other. Users can join one server but follow people on other servers. Because it is decentralized, the rules, moderation, appearance and focus can vary widely from one instance to another.History
