> Downvotes here literally slowly erase content that the community doesn’t like;

Most of the time downvotes are used to erase abusive content, but it's shocking how quickly some of the well-formed opinions in the content sections go gray if they don't agree with the popular opinion on HN.

At this point, I almost don't bother replying to HN comments if I know they'll just be met with waves of lazy downvotes.

The invisible hand of HN creates an echo chamber by teaching us not to post "content that the community doesn't like", which is often just comments that disagree with popular sentiment.
