@spitz … continuing the other interesting fedi platforms thread.
plus one for firefish (and related platforms, namely misskey and iceshrimp (?, a recent fork of firefish)) … basically the answer to what if microblogging were richer, more interesting, more featurefull, more fun, nicer looking, not so much *micro-*blogging and not at all concerned with being a twitter clone.
Akkoma (and its predecessor/older fork pleroma) are maybe worth checking out, though they’re more popular amongst self-hosters and for good technical reasons it seems.
Friendica is the fedi alternative to facebook. I generally don’t hear good things about it, but it’s still actively developed and seems to have an active and dedicated (albeit small) user base. Hubzilla/Streams (developed by the same founding dev of friendica) are in a similar position AFAICT.
In case you didn’t know … kbin is a sort of alternative to lemmy, where it has very very similar community functionality but with some features that integrate more with the microblogging platforms.
Otherwise, you’ve got Pixelfed, an instagram-like alternative, popular and actively developed, and the sort of blogging tools/alternatives I don’t too know much about: writefreely, micro.blog, the fediverse wordpress plugin, and microblog.pub (niche self-hosting platform).
The Fedidb Software page is probably a good guide to what’s out there and what people are using.
