You know what doesn't gratify my intellectual curiosity? Stories about beginner level Vim, or stories about programming iPhone apps. The first because I am a fairly advanced vim user. The later because I don't really care about iPhone dev. Perhaps that means they don't belong HN.
Or perhaps it means that not every story on this site exists for me. Many of the stories here do qualify for my intellectual curiosity. Many stories I would like to see discussion on are not discussed, and many that are discussed I don't care about. Perhaps I should go to every story about basic Vim and declare that they just don't belong here because my intellectual curiosity is not properly being pandered.
Or perhaps everyone should grow up a bit and not chicken-little every story they don't like but which gets major points. It always baffles me how:
If you had to reduce it to a sentence, the answer might be: anything that gratifies one's intellectual curiosity.
a statement that implies in itself that it isn't the end-all-be-all definitive rule, gets turned into some sort of hard rule. And that hard rule application somehow ignores the fact that some people find different things interesting, if those things disagree with the reader's personal taste.
