>people will use downvotes as a substitute for disagreeing, despite that being explicitly against its true function. //
Early on with HN pg stated that downvoting for disagreement was proper behaviour on HN. My opinion is that's wrong but, in contrast to other fora, downvoting to disagree is thus explicitly a part of proper behaviour here.
That said, I don't care about the points, it's a matter of social value - if you don't know why people are disagreeing then you can't address that concern or reassess your own position, the downvoted adds no value whilst a comment may.
