What do you mean kbin doesn’t really support microblogging?
I could be wrong about this … but as I understand, you can’t see a feed of microblogs/posts from people that you follow. Instead everything is viewed through magazines, which pickup microblogs but combine them with the ordinary threadiverse content posted to those magazines. Following people and viewing their personal posts is, I’d say, the essence of microblogging.
Not a criticism of kbin at all BTW … easily the youngest platform on the fediverse but doing quite well it seems with already a fork that’s doing well too (mbin).
