Mastodon (software) - Wikiwand

Mastodon (software) - Wikiwand: Mastodon is a federated social network, with similar microblogging features to Twitter, but administered as a decentralized federation of independently operated servers running free software. Each user is member of a single Mastodon server, known as an "instance", but can communicate with users on other instances as well. Users post short messages, called toots for others to read, subject to the completely adjustable privacy settings of the user and their particular instance. The Mastodon mascot is a brown or grey Proboscidean sometimes depicted using a tablet or smartphone.
