What exactly is Misskey supposed to be? - eviltoast

Most of the other Fediverse platforms are pretty obvious to me as to what they’re meant to be alternatives to. Mastodon for Twitter/Threads, PixelFed for Instagram, Lemmy for Reddit, Matrix for Discord/Slack… But I can’t quite place MissKey. It doesn’t really feel like any other social network I’ve seen before.

I’ve tried looking around, but most of the instances I’ve seen are either in Japanese or Russian so I can’t really tell what I’m looking at, or have no active users to really see what the engagement is supposed to be like.

Can anyone fill me in on what MissKey is meant to be an analog to or how it’s meant to be used?
