Downvotes are not only misused for expressing disagreement. For example, this comment https://news.ycombinator.com/item?id=9489042 https://news.ycombinator.com/item?id=9489042 of mine had in the beginning several downvotes. Several people on HN downvote you for saying something is not understandable for you and asking for a transcript. Is this really how we want HN to be? Stop misusing downvotes.
