A big problem is prior knowledge. Most papers incrementally increase knowledge so by necessity they have to assume the reader knows it, lest they find themselves repeating it alot. How far back are you expected to go to help your audience understand?

The answer in most of academia is: not at all. You're expected to have learnt everything in the field up to that point. Academia is for academics and generally doesn't care about impact outside of academia, who seldom understand it anyway (because of its academic nature).
