I guess the best I can offer is the general principle that intellectual curiosity is the guiding value here (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor...) , and indignant/flamey/ranty comments tend to be out of that register.

One important aspect of this is repetition. If a comment is repeating something that has been said many times before, its curiosity value approaches zero—and indignation makes that happen faster.

Conversely, the more new information or unexpected twists a comment contains, the better it is for curiosity.
