OK, since this post exploded (which means there is a lot of interest in #Firefish!), and since some people might have misinterpreted some of the things I said, let me point out a few things:
I am NOT saying that Firefish is necessarily dead. I hope that this post works as a wake up call for Kainoa - whenever he sees it. If nothing changes (either Kainoa getting more involved again or sharing responsibilities or whatever), yes, it will be dead. Really hope something changes drastically, a lot of people love this project.
I am also NOT saying that #catodon is a continuation of firefish, but a different project. Honestly, if that's all you're looking for, there are other project which might be more suitable - we don't want to mislead anyone. We will gradually change quite a few things, the goal is to make it a great and easier to understand all-around software for fedi communities, so for example some of the misskey-specific features will go. In a way, it will sit somewhere between Mastodon and Misskey. So our goal is NOT to replace/continue firefish but to find our people, who will be interested in what we -and not firefish- are trying to do with the platform, and maybe do it together.
Hope this clears everything up.
