Weird things I keep noticing on Lemmy... (discuss.tchncs.de)

  • Number of votes for posts and comments differ from instance to instance (sometimes drastically, 300 vs 30 for example)
  • Number of comments differ from instance to instance (meaning you can "miss" some comments on one instance, because they simply aren't there)
  • Order of posts and comments differ from instance to instance (even with the same sorting option)
  • If you leave the post open in the tab, you can come back to that tab later, only to see that it is a completely different post than the one you opened, but the comments are still from the original post.
  • On the front page, more post will sometimes randomly start loading from the top, those posts usually come from a specific community and are old posts (sometimes very old)

Does anyone else experience this?
Are those simply bugs, "features", problems with specific instances, or just the shortcomings of this kind of platform?

To add to this, currently Lemmy (and maybe other federated sites) handle each vote and comment as a single http request, so propagating votes and comments takes a LOT of processing power and bandwidth.

However like all protocols, I think ActivityPub will solve this issues by sending aggregated requests (sending batches of votes and comments instead of one by one)
