Mastodon is a decentralized, federated social network, with an interface similar to Twitter. Because Mastodon is federated, this means that users of one instance can follow and interact with users on many other Mastodon instances.
Yamabi.co is a Mastodon instance for fans of the Touhou Project series, although you are free to post about whatever you want here. It's a great place to meet others with a mutual interest in Touhou.
