It's important to be aware that this is a mechanical process. The first comments to appear in a thread are there because they're the fastest to write, not because they come from "the average HN commenter". Another way of putting this is that the initial comments tend to be reflexive rather than reflective: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&sor.... (Objecting to objections can be reflexive also, but at least the second wave tends to be more substantive and charitable.)
