Hi there mbin dev here. The interaction with mastodon is possible: you can follow people, you can see posts from people from mastodon (just in the “microblog” tab, not the “threads” tab), but it has not been the main focus since mbin was created and has therefore not made huge progress. We have plans to improve the microblog side of things (or at least I have), but there were just so many behind the scene problems with the code that needed fixing (and still need improvements) so we focused more on that.

I will not promise anything, but I want to have threads and microblogs in the same list and I am thinking of adding a “timeline” tab that works more like the microblog style that people know. However development has not started on that, yet and we therefore do not have a release with which this is expected or even an ETA.
