I’m guessing it has something to do with mastodon, since microblogging is interoperable with mastodon like how threads are interoperable with lemmy.

Example post:
https://kbin.social/m/technology@beehaw.org/p/434431

I can see this post on beehaw here:
https://beehaw.org/post/565892

But next to it in technology@beehaw.org are threads that show up in the threads section of kbin.social/m/technology@beehaw.org

How are threads and microblogs distinguished on different instances if they’re both interoperable with both lemmy and mastodon like this appears to be? How can you access the general mastodon feed from kbin?
