@autonomic That's great! We're currently organizing on xmpp:email@example.com?join if you'd like to join us. The general idea is that a lot of services are run by individuals and it would be nice to have something that's less likely to be shut down when that individual gets bored, or that has 24/7 support because people in different timezones can restart things if they catch on fire and what not. It's early days though, so we haven't decided if it would be public or just for members.
Sunbeam City is a anticapitalist, antifascist solarpunk instance that is run collectively.
