Reddit Migration

Ok, maybe I’m doing something wrong, and I might have language wrong here, so correct me if I’m way off the mark.

But I can’t figure out how to tell if I’m about to go to a comment section of a posy that’s from a kbin magazine or some other group’s magazine equivalent.

My understanding, as someone using the mobile site:

• I have an account on kbin.social
• Kbin.social is an instance of. . . Something…
• kbin.social is federated with other. . . instances(?) like lemmy.world and sh.itjust.works.
• because of this, we who have accounts on kbin.social can interact with posts from communities/magazines/whatever their equivalent is from Instances(?) that kbin has federated with.
• the home page on kbin.social is the equivalent of Reddit’s r/all
• the home page on kbin.social will show posts from other instances we’re federated with
• presumably there is some way to tell whether the post we’re clicking on is from a community on kbin.social, or a community on a different instance
• with some posts it’s easy, because there’ll be a little (lemmy.world) or similar under the title
• some posts, however, have (kbin.social), and then when I click to go to the comment section, it turns out it’s from sh.itjust.works
• when you click on a post originally from another instance, it shows a warning at the top of the page, that it may be incomplete. The name of the instance is only shown at the bottom of the page, not in the post information.

My questions:

1. is my language right?
2. How can I tell, before clicking on a post, what instance it’s from?
3. assuming that both kbin.social and lemmy.world both have a “books” magazine/community/etc., how can I tell if the post on my home page from “books” is from kbin or lemmy?
4. how do I see a feed of only my subscribed magazines?

Thanks!
