I’m curious, what was hard to figure out? I assume it was something federation-related?

I never really had a problem figuring things out (though I’m sure there are still things I could learn). The only difficulty was that when I was subscribing to communities, it was sometimes hard to know which was the “main” or “most popular” community. For instance, there are half a dozen fairly big gaming communities spread across various lemmy instances. Some get more posts, some get more comments. Reddit also had a few different gaming-related communities, but it was easier to figure out which were the bigger ones and which ones had a slightly different focus.
