Not even microblogging, jut blogging in general. ActivityPub could be a replacement for RSS readers. I consider a platform that allows you to mix microblogs, blogs, podcasts, videos, and livestreams/events the "endgame" - all of which can be done with ActivityPub (albeit with different projects today). Unfortunately this is not the type of project that I would find interesting at all to write.
