What do you notice about the comments on this post? https://piefed.social/post/555259
The post was made in the news@lemmy.world community and other posts linking to the same news article were made in technology@lemmy.world and in askusa@discuss.online. 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.
But the comments are still separated out by community in the example post. You can still see the discussion in !technology@lemmy.world as a stand alone, isolated discussion, but if you scroll further you also get the !AskUSA@discuss.online. I assume if you reply to a comment, you’re then replying in that community, but I didn’t test that.
Lemmy shows links to all the posts about the same link (I think) so it doesn’t feel like an improvement over that
