What do you notice about the comments on this post? https://piefed.social/post/555259

The post was made in the [email protected] community and other posts linking to the same news article were made in [email protected] and in [email protected]. 3 different posts in 3 different communities.

PieFed de-duplicates them and only shows the post once in the timeline and when viewing the post all the comments on those 3 posts are shown in one place.

The fragmentation problem is solved.

What happens when three different users post libks to the same article? Or when the test is different? Basically how do you match these posts?

They are matched by the url of where the post links to. So this only works for posts that have a url, not discussion or image posts.

what happens when there's 2 different posts in the same community with the same URL, example:

https://programming.dev/post/8880813

https://programming.dev/post/1721399

(I can't find a more recent example right now)

Those comments get merged into one tree. I think, didn't actually test that.

This is or at least was a problem with cross-posts in the same community in Lemmy as well. I think now Lemmy just prevents posts with the same URL to be counted as crossposts when they are in the same community.
