Misskey is an unprecedented forking party. Sharkey is one of the many forks. Maintained by the Blåhaj folks, if I’m not mistaken.
Iceshrimp is another one to watch. Specifically Iceshrimp-NET, a full rewrite to fix the performance issues that probably play some role in why these forks often meet such sad ends.
Ah, yikes - that’s what I thought. Never imagined a French software company could lower themselves to M/D/Y haha.
