Paul Graham, who started HN, is one of those people: https://news.ycombinator.com/item?id=117171 . Generally, HN strongly discourages "me too" or "i agree" type comments. We prefer to just upvote comments in order to keep discussion threads interesting and on-topic.

It's pretty much upvote to agree, downvote if it doesn't contribute.

Of course the next highest child is then always the next most agreed upon counter argument since they should reply instead of downvote, which can make HN feel a bit contrary but full of good discourse

Isn't that the recipe for an echo chamber?
