Earlier today I was sitting in a presentation by a faculty member who included a slide with an email quote from a former student who did exactly what you said right before the presentation. It absolutely made his day. And I know the former student and have a hunch he reads HackerNews.

This also made my day because I saw the real-world impact of something on HackerNews. And perhaps it will make your day to know your comment has influenced more people than the poster you were replying to.
