Threadiverse and microblog, or topicverse and userverse?

Threadiverse and microblog, or topicverse and userverse? #fediverse Something that was bothering me is how comments in microblog platforms usually split and are sorted in the same way as most threadiverse platforms do, just with a smaller scope, but still functionally the same. But also, some threadiverse platforms sort comments rather linearly, similar to board forums. While talking to someone a while back in a conversation more or less in this topic and that I think I accidentally deleted (oopsie daisy), something that came to mind that I said is how in the “threadiverse” you follow topics, while in “microblogs” you follow mainly users, with tags being better at saying “this user is talking about this topic”. So a few minutes ago, a thought came to mind, wouldn’t “topicverse” and “userverse” be closer to the scope of their referred engines/instances? Or did I get the idea wrong and went on some random tangent? @fediverse@piefed.social
