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?
kbin by default throws everything that isn’t formatted like a kbin thread into “microblogs”. For whatever reason that thread on beehaw had an issue so it got put in the microblog section. I saw a similar issue result when one beehaw user tried to include a hashtag in the title of their thread, breaking it for both lemmy users and kbin users (lemmy displayed it weird, kbin put it in microblog section).
threads are essentially “special” microblogs with extra info. Mastodon posts will show up usually under the microblog section, but sometimes may end up in a thread depending on the situation.
On a technical level, lemmy users, kbin users, and mastodon users can all see the same content, just formatted differently.
