@deutrino @quinn yeah. I used to be pretty active there, years and years ago.
The sad thing is Diaspora* used to be the biggest of the FLOSS federated social networks, and they kinda acted up because of this. Never properly documented their protocol, I believe, and were definitely not interested in implementing any other protocol.
It's a sad irony that at some point Mastodon and broader ActivityPub-verse grew way larger than they've ever been and now they're kinda in a pickle.
