I think we'll actually learn more during this experiment with less rules on format up front.
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.
YC partners complain about this all the time too.
> not a single one has mentioned how it's a business and how they will make money
I hope you asked them!
I think the equalitarian thing to do would be to encourage apply hn's to be as self contained as possible to avoid biasing on the quality of the landing page or video or whatever else would profit from the exposure
