I'm surprised to this take, because I feel like I see math stuff posted here fairly often, and often with a large number of people commenting on it in substantive ways. Often times the math savvy crowd will even help explain stuff to people like me who are not particularly fluent in advanced math.

> software development site ... you need to consider your audience when posting links to this site ... a link to a really good cookie recipe ... for programmers

That is really your interpretation only - and it directly clashes with the explicitly intended: "intellectually curious" (which will be, if not polymaths, at least open).

Of course an intellectual curiosity space hosted around the world of startup enterprises will attract membership of people with experience in engineering.

If you check the submissions, it should be immediately evident that there is no closure.

I see plenty of things shared here that don’t fit your preconception of what is a fit for a site you don’t operate.

> For example, if I posted to HN a link to a really good cookie recipe, it wouldn't be a good fit for this site.

Going to have to disagree with you here. That would very much depend on the particulars of and circumstances surrounding the recipe. This is a site for anything that would interest the typical hacker (whatever that actually is) after all.

I'm frustrated I can't downvote you more than once. You are the example of anti-intellectualism that is allowing the world being controlled by dumbed down mass media.

If I consider the hacker news audience as "smart people" and/or "people with curiosity about science and technology", a couple of equations are exactly what should appear in every single post.

Have you considered that you are simply not the audience that Alex or speckx had in mind? It would be healthy to recognize this simple fact and move on while letting the intended audience (Hi! Longtime HN member for over a decade!) enjoy it.
