I recall this was the top-voted comment (rightfully imho) until shortly after someone suggested that the author was depressed instead of being reasonable... Now it's at the bottom, and lots of "wow, this is super-interesting" comments are above.

I never know what to make of the psychology of this/my community (tech, specifically), but the dynamics here on HN always provide me lots of "food for thought" to overfit :)
