"I see a ton of Show HNs in which I have no idea what the product does (either because the website copy is vague/confusing or because I don't know the market). "

This problem happens to me so much I just ignore most Show HN's. I open a mainstream website to find who they are, what problems they solve, their solutions in a high-level way, and datasheets or whatever giving technical specifics. Many Show HN's here are one page of stuff that I read and read all the way to the bottom before I even begin to grasp what the hell they're doing.

That could just be due to them working in a specialized niche with its jargon. Yet, I have an intuitive feeling that it's often a problem with the presentation because they're usually intending to reach (a) current, jaron-knowing users of specific tech and (b) future users who know the concepts or needs but not that specific tech & jargon yet. So, at least a few sentences or a paragraph for people in (b) might be helpful. And at the top to save time.
