Apart from two (two!) comments, of which one is [dead], expressing confusion about why this is important, there seems to be no divide. There's really no need to translate anything to "HN crowd" (by that I assume you really mean hacker community in general). Competent programmers (hackers) and really highly technical and highly competent people tend to appreciate good design (not just graphical design, but design in general) even if they don't know particularities of it. It's a matter of taste, and good taste is objective (PG already articulated this better than I could do[1] [2]).
A couple of anecdotes:
- TeX came to be because Donald Knuth was horribly annoyed with the low quality of then nascent digital typography in the first edition of The Art of Computer Programming. AMS Euler[3] typeface is a product of his collaboration with Hermann Zapf.
- The first practical application of Unix was to run the typesetting in troff for technical documentation at Bell Labs.
