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.
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.
