Nowhere is this urge (and the reward for it) stronger than HN. In the majority of comment sections, the top comment is one that pounces on a few words from the posted article, however tangential or self-serving.
However, HN is also one of the few places where it's not uncommon for me to see people push back on it. And often comments that "pounce on a few words" are offering valid criticism on only that part IMO, while still accepting the larger work that's been posted.
