This page looks like you can't decide whether to create a lightly interesting tech demo[0], an avant-garde art project[1], or an introductory article on s-expression markup templating.
Pick one. If you want to do all three, do so separately.
Regarding the project itself, as someone with quite a bit of functional programming experience, I don't see much appeal over standard HTML (at the low end) and DOM-aware templating (e.g. JSX). The Lisp language family has never delivered on the promised benefits of using an AST as the textual encoding, and to the extent nested expressions are useful in markup I think HTML/XML gets 90% of the value with 5% of the frustration.
Regarding your HN post's question, one part that did activate my "crazy sidewalk preacher" detector was the text on beauty of mathematical constants and symmetry. The following quote is exactly the sort of thing I would expect to read from a young adult who is losing their connection to consensus reality:
the strangest of transcendental numbers, π = 3.141592653589793,
whose decimals are totally randomly distributed, (high
entropy), is captured in a beautiful, perfectly determined
series, (high neguentropy). Our (decimal) representation of
numbers is decidedly poor and I imagine that in the noosphere
minds use continued fractions to manipulate them.
It's endless.
I don't mean to be insulting when I say this, but that sounds like a Terry Davis quote. If you find yourself thinking in that mode frequently, it might be worth asking a mental health professional for a screening.
[0] As a sort of personal knowledge base, I find the lambdatalk format interesting. Horizontal lists of narrow columns is a classic of printed text but rarely encountered on a screen, and I like how the figures (formulae, code blocks, etc) are integrated into the prose.
[1] The angled subsection, bizarre choices of example content, and long lists of links to subpqges(?) come across poorly in terms of information, but are aesthetically pleasing in a sort of surreal way.
