Strong agree.

A while ago lemmyworld temporarily defederated from my old instance, and the feeds + activity dried up pretty quickly.

They refederated after a few of us hopped on to the matrix to try and find out the reason behind it, but it showed how much mass Lemmyworld has. Even if the communities are distributed across many instances, most of the users are visiting from Lemmyworld.

Things may be a little different now though as users have started to spread out a bit, and of course we have instances like Beehaw and Hexbear that aren't federated with lemmyworld, but are running just fine.
