edit: I think I read HN comments more than HN articles. Interesting
Your comment suggests that you at least read the last section. : )
But still, that's headings and structure working as intended: You skimmed it, got a good sense of what it's about, and decided it wasn't for you.
I'm assuming that if I had presented the same information in a different way, it still probably wouldn't have appealed to you if you could tell from the headings that you weren't interested.
