No I am saying to me it seems like the vast majority of confusion for new users is giving them this super long detailed explanation of federation, and/or users trying to figure out which instance they should be joining. As a new user all you really have to know is to go on lemmy.world and signup and its just like reddit.

What I said is what I've done and have had zero to worry about.

Yeah thats fair on your communities disappearing. Not really a common things thats happening though, and not something youd really notice until you used it for a while.
