If we do try to educate users then at least we should do this gradually. Forcing someone to learn keys/relays/etc when all they wanted was to post a "like" or write "hello world" makes no sense. There should be a super-easy way to start and get the value user expected, but then a gradual process of explaining why things are the way they are in the context of tasks that users are trying to accomplish. That's probably 100x harder than just snapping a couple explainer screens here and there.
