m/dance was created very recently on kbin.social and has only a few posts. Still, if I search for its URL on lemmy.world it is visible and I can subscribe, though I can’t see any of the posts: https://lemmy.world/c/dance@kbin.social

I recently created the community c/survey_polls on lemmy.world, but when I search for it on kbin.social it is not visible. I can see the cross-posts I made on c/general and c/newcommunities, and looking at my profile through kbin.social my first post to c/survey_polls also doesn’t seem to be visible.

My point is, what communities/posts are or aren’t visible across lemmy.world and kbin.social? Do posts from one website only appear on the other if the community already has subscribers? Or is there some sort of time threshold?


To add to this, when looking at the post through lemmy.world you see 1 comment, while on Kbin there are 3. I’m even more confused now.

    I think this is true for both platforms - instances don’t federate communities (start polling for updates) until one user searches for that community. It takes a second search (at least in v17 lemmy, might be fixed in v18) to get the community to start showing. In Lemmy I think when an instance starts federating a community it also pulls the latest 20 posts, but given your example I’m guessing that must not be true for lemmy pulling in kbin magazines (not sure which side isn’t doing it, I’d assume the kbin side since lemmy instances seem to be coming in with those 20 posts).
