No ill will here, but I may have some insight for you. HN is a community of "hackers". Hackers are builders. Hackers take things apart and understand how they work, whether that be a physical thing, or a conceptual thing. Given the parent poster's example, I think they're bothered by your incorrect statement regarding the TokyoFlash watches. A small point, yes, but many hackers have a penchant for accuracy.
