I've been on KBin Social, Lemmy World (least 2 dedicated accounts), KBin Run, Mastodon, Blue Sky .etc
Blue sky is not on the fediverse. They've decided to come up with their own federating system from the ground up, which I think kind of squandered what could have been a pivotal opportunity to help facilitate a mass exodus from Twitter, contributing to fragmentation and confusion.
But anyway. I think they intend to have their own version of federating soon but I don't think it's up and running yet.
Thank you for that read. Seems to completely miss the point of federation. The core motivations related to improving choices about how user names and federation structure works, and forcing their domain to be the mandatory user facing side of the whole network could not possibly miss the point more except by being actually centralized. Mandatory firehose relays of the entire networds data that can't be federated or defederated that could be prohibitively costly to host?
And the complexities under the hood that attempt to square this circle are infinitely more confusing than explaining Mastodon instances.
