Values differ.
Personally, I frequently find the most value in comments trying to articulate hard to understand concepts: they seem to resonate with me and help me understand a topic, even more when they reach valid yet counterintuitive conclusions.
I guess we each use HN for our own purposes. Personally, I see it as a forum of bright minds to explore complex concepts such as creativity, or the place of passion in one's work .
"I hope english is not your first language" - What do you care? You are just being a dick.
For example: "too many renonciation might kill up the sparkle for good." makes no sense to me.
