If you have to explain a joke it loses its meaning.
If you have to explain UI, it loses its meaning.
It should be self explanatory.
People here say Lemmy's UX is fine, and then give a paragraph of instructions a user should follow to get started.
They should just be able to start scrolling immediately, and if they want to interact they should be asked to create an account, and a instance suggested.
Can't say I agree with all of that and some of it is factually incorrect (Jeroba is the "official" app, for instance, and Interstellar is pretty damn good for another).
Much of what they complain about isn't exactly UX per se either.
