I have a GoToSocial server, which is pure AP, not Mastodon. Misskey is still a microblogging platform, right? One of the people I interacted with a lot when I was trying it ran a Misskey server, and she used it like a microblogging tool.
It’s the modality of it. There’s a category of servers that follow the Twitter model: people follow people, and posts are usually short and frequent throughout the day. Then there’s the Reddit model: people join communities, and tend to do more periodic binge browsing.
Misskey - as I understand it - is a follow-the-person, shorter post model; the Twitter model. Lemmy models after Reddit.
I prefer the community model.
I think there are several servers that don’t try to match any particular dominant player.
It’s really down to the follow-person or follow-community model. AP supports both, but I’ve seen few servers or clients that support both. Which should be possible; it’s something that frequently annoys me about every Lemmy client I’ve tried: sometimes, there are people I’d like to follow, and get everything they post, regardless of community, in my feed.
