You guessed that he avoids mentioning his school by name to avoid the high expectations along with it. To operate that this guess has to be true is, at best, disingenuous.
I'm going to go out on a limb here and theorize that, since the start of this topic you've consistently taken Mr. Guo's side, pedantically pointing out rules and etiquette, deflecting from what he actually said, not responding to actual quotes from his writings and posts and your general literal mindedness, that you are indeed one of the name-brand school graduates that he feels is victimized by the boorish snobbishness of the tier-1+n school grads.
Spank me if I'm wrong. But it's the only thing that adds up.
Either that or you are a tier-1+n school grad who's been guilt tripped by this article into rethinking your prior maltreatment of the elite school kids.
This is old by now, but you should be able to see from my profile that I am at a large, middle-of-the-road state school. Note that I haven't actually defended the authors position, only clarified what he said. I'm not sure if I agree with his position. But I've seen very little discussion on what he actually said. I've spent all of my time explaining what he did and did not say. I've spent no time (that I can think of) defending the position he took.
I also like to avoid long, drawn on point-by-point posts, and try to keep things focused by responding to a person's thesis.
Pointing out etiquette has nothing to do with this article, and everything to do with liking HN as a place for civil discussion.
