>HN can potentially learn from this.

Learn what? The whole thread is basically a fond pop at HN, with the usual 4chan dribble thrown in (like the faggot/nigger shock commentary).

I'm not sure how the vein of commentary about the headlines being business/startup oriented is a negative criticism, since that's the point of HN - and if anything, the business side of the forum has been dying off for quite a while.
