Festive Eugen is a user on mastodon.social. You can follow them or interact with them if you have an account anywhere in the fediverse. If you don't, you can sign up here.

I am also helping some folks host/start their own instances, for example:

@erol who's making an instance for Turkish people who don't like being censored by the Turkish government on Twitter

@noxville, a Dota 2 analyst who's trying to bring Mastodon to the Dota 2 community
