Misskey is microblog compared to Lemmy or Kbin , but still it’s fun to use albeit more demanding on resources. While Kbin/Lemmy see karma as numbers, Mastodon (main branch) as likes, Misskey have emoji’s so you can convey your feelings without making short replies.
Sure some people will say that’s dumb or useless, but hey when you see some art and having only ❤️ instead of 🆒 or :cool__i: or :otoge_rank_aaa: and so on.
There is many other neat features but the main point of this comment is.
You can join in on conversation without restricting yourself to limitations imposed by soft/server one use.
Add on top that you can self host which is not for everyone but people having their whole identity tied to their own space instead of Twitter/Youtube/Twitch etc.

Which would be true if Misskey wouldn’t send error and deny me sending message, so we still far off in that point.

Everyone gives solid advice, so I will point you to trusty https://fedidb.org/software .
Mostly to see stats of Fediverse but also the soft that is available. Maybe you find one that suit you.
