Take this post, for instance:
https://fedia.io/m/lemmyworld@lemmy.world/t/6403/Does-lemmy-world-allow-criticism-of-the-CCP

In theory it shouldn’t really matter which instance you happen to be clicking a link into, as part of the point of federation is to have a shared group of content people from different instances can view and interact with.
I think currently though it feels off because with federation being either slow or not working, you don’t know how stale the comments you are responding to are, or whether your own post will even me seen in a reasonable amount of time or at all.
