Someone actually said it spot on on Reddit in a random post saying the problem with Lemmy are Devs, they overcomplicate it to be "different" trying reinvent the wheel when there's no need. Like "Instances" just call them servers.. it's like learning a new language for the sake of being different, it's pointless and confusing for new users.
I like Lemmy but I think it's still too confusing a construct and not enough streamlining of new and different content. Will it change.. time will tell but I think if it doesn't quickly it will just be a niche thing people use as an alternative but nowhere close to where its trying to be.
The servers (instances) aspect and different communities (forums on topics) on different servers and servers blocking others, is a mess if I'm being honest. It's the biggest flaw. I still find it hard to find communities of topics I want..
