I must be completely "dull witted" then. When I first started looking into lemmy, I went to the official "join-lemmy.org" website, clicked on "join a server" and picked one of the top listed recommended results. It just happened to be a VERY small and VERY new instance. But as a completely stupid dull witted new user who knew literally nothing about lemmy, I didn't know any better.

After joining that instance and looking for communities on it, I only saw the local communities plus a few non local communities from larger instances and I legit thought that's all there was on lemmy. I mean, it was clear I was seeing the local ones, and it was clear I was seeing some nonlocal ones, who why tf would I expect that I wasn't seeing everything?

Your perspective is tainted by the fact that you know how it all works. People new to lemmy don't, and I'm telling you that the onboarding and community discovery process is dogshit. I beg you to try considering things from the perspective of a newer user.
