Why do comments differ across instances?

3 years ago by burningmatches to c/feddituk

If I visit a community from Feddit and then another instance, the comments often differ. I understand there are some issues with defederation between some instances, but this doesn't seem related to that.

For example, here's the post-race discussion on the Formula 1 community on Feddit: https://feddit.uk/post/320484

And then the same discussion on lemmy.world: https://lemmy.world/post/950479

I don't understand why a significant number of comments aren't visible on Feddit.

Sometimes instances are overloaded which cause federation events to timeout and be dropped. Since federation is a push event when this happens, it cannot be recovered

Is that not a pretty big weakness to Lemmy? I know it's never going to be perfect, but if Lemmy is to appeal to more people I feel issues like this add friction and makes Lemmy appear to be a little quiet/confusing as a result.

For instance, I have two Lemmy profiles - one on Feddit.uk and one on FMHY - both have different comments on the same post in !gaming@beehaw.org

I say, stop worrying and enjoy the chaos! So you miss a few comments here and there, so what? There's plenty more around and as the traffic increases more and more, we can't keep up with all this content anyway.
