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?
It's federation. LW users can post to sh.itjust.works as easily as gmail users can send mail to yahoo mail addresses.

Yes I get the principle, I'm just having trouble with the mechanics, but not quite "just as easily" - posting or commenting in a community hosted on sh.itjust.works seems to require remote-subscribing to the community from lemmy.world - which I've done and it's now pending. Waiting to see if that does the trick.
