No idea how I got there but somehow I saw this post somehow on sh.itjust.works, about a prefab house that was found floating in the Pacific. I wanted to comment but the only login I have is on lemmy.world. Notice the post is from The Picard Maneuver, whose posts I’ve seen many times, and it says lemmy.world above their name.
Lemmy.world has a whitepeopletwitter community but the newest post is 2 months old. This one is from 10 hours ago. Search on the lemmy.world main page for “Minding” turns up a bunch of posts going back months, but this one isn’t there.
I thought I understood how federation works but I’m stumped. Is this really a lemmy.world post? If not, what does the presence of “lemmy.world” on it indicate?
Crossposting.
Crossposting is basically using a URL already attached to a post into another post. So if, I crosspost a picture of a squirrel originaly posted by a .world user in !aww@lemmy.ml to !squirrel_spotting_society@lemmy.sdf.org, the post will be linked to .world as it is the original url from which the image is federated to other instance.
Here is a link to an example: jlai.lu/post/17799614
