Take this post, for instance:
https://fedia.io/m/lemmyworld@lemmy.world/t/6403/Does-lemmy-world-allow-criticism-of-the-CCP
The user and magazine are both from Lemmy.world, but next to the title it says (fedia.io). What does that site in the parentheses mean?
the kbin.social instance shows the instance name that the post comes from. it also has a lot of various lemmy and kbin instances posts on the home page. It seems the front page here is more things posted directly to this instance. However, there have been server changes which might have messed up the federation syncing.
Just go to the kbin.social page and you’ll see the difference
