So like, how does Lemmy work?

When I click on a post, let’s say Lemmy.World, that server sends me the page over the Internet. I get that part. But how does it do comments? Does it tell my phone to go ask lemm.ee and blahaj servers, etc, and fetch the comments?

And why does a post on lemmy.world have have a blahaj URL when I look at it? Is my server making a copy?

    So the size of the home server grows over time as it stores text comments from other places it federates with.

    One thing I’m confused is if Lemmy1 and Lemmy3 aren’t subscribed to each other, but they both comment on a thread on Lemmy2, will they see each other’s comments?

      The size of all involved instances grows since they all store a copy.

      if Lemmy1 and Lemmy3 aren’t subscribed to each other, but they both comment on a thread on Lemmy2, will they see each other’s comments?

      Yes, when lemmy2 receives a comment from an outside instance it will then send that comment to all subscribed instances.
