    shortDescription: Connecting the world through thriving online communities
    longDescription:
      'Mastodon is a free, open-source social network server based on
      ActivityPub where users can follow friends and discover new ones. On
      Mastodon, users can publish anything they want: links, pictures, text, and
      video. All Mastodon servers are interoperable as a federated network
      (users on one server can seamlessly communicate with users from another
      one, including non-Mastodon software that implements ActivityPub!)'
