By 'quality' or 'performance' I mean the metric by which a post (and its children) is shown higher or lower, or even auto-collapsed. I think reddit just counts a ratio of upvotes to views (ofc downvotes too). It is possible that users collapsing a comment/subthread also has some weight. Would make sense. > And, importantly, the quality requirement for the post increases the higher in the total hierarchy it is: root-level post, top-level reply to a top comment, and so on What I mean by this, is that the more prominent a place a post holds, the better it must 'perform' (per the above definition). Prominence being mostly just how high on the page it is.
