Papers are written to peers. It shouldn't be a "murder mystery" for them (that doesn't mean it shouldn't tell a story). You have to write to your audience. If a paper was written to a general audience, instead of peers, every paper would have to be a novel.
I'll admit that sometimes I'm frustrated with HN comments on arxiv articles. Despite being a nerdy forum most papers aren't written for this audience. Hell, I have a PhD and most papers aren't written for me. Nor should they. I'm perfectly okay if I don't understand a paper. Arguably the hardest thing about a PhD is learning to be comfortable with being dumb and willing to work on becoming less dumb (you're never not dumb, only less dumb)
