So I thought that you should be able to take https://programming.dev/post/50678, paste it into the search box for lemmy.world, and get the local version of that post. But that doesn't work for your particular post
However, another programming.dev post does work
I don't know what the difference is.
FWIW I subscribed via my local instance after finding some posts while using the Lemmy search function.
I found this thread which says you can use the search bar to pull up a permalink in your local instance. Seems to work for me, though I'm with you that something more seamless would be nice.
Edit: this is only on the web UI. I haven't figured out how to do this in Jerboa.
Sorry, but as a meat popsicle, I'm not interested in commenting on your site.
