Kbin is the first Reddit alternative I looked at and i liked the UI so I stuck with it. I kind of assumed everything would be kbin. I thought I understood things. I thought it was kbin and lemmy separate but they federated and so I’d be able to access lemmy stuff from kbin. Which I guess is true. But now I’m confused. I look at all, and I see a post in m/[email protected] and the post is from lemmy.world and it’s devs. I’m not subbed to m/main, so did Ernest curate /all and add it? Are people cross posting from lemmy into sh.itjust.works? I feel like I need a drawing or red string diagram.
But like… how did all get created? Is it literally just pulling from all federated instances?
Your instance becomes aware of the existence of another instance when just one user subscribes to a community there. From then on it will appear in all.
A lemmy.world user posted in a sh.itjust.works community. Then it’s propagated too all federated instances via a protocol called ActivityPub.
Whenever somebody subscribes to a community in another instance, that instance starts sending posts and comments to your instance (kbin.social in your case). The front page of any instance is just the all of the posts and comments that exist on that instance, sorted.
