Woah, that's a really thoughtful feature. Is there somewhere I can find all of the, like, rules of HN similar to this one?

Sadly, I don't think so. The best source I know of is https://github.com/minimaxir/hacker-news-undocumented, but it's missing a lot of stuff like that bit about the reply button.

I learned about the reply button because I too was once wondering why it sometimes doesn't appear, and I Googled it.
