The way people interact with HN has a way of influencing the comment stream in nuanced ways. Not releasing all of the information about scoring publicly (or even the score) is an experiment about how such things affect the conversation.
One may not like it, but the general consensus is that "me too" comments just clutter the conversation and don't add anything. If you agree (or disagree, but appreciate the argument) then up vote.
That is my point. I understand that this site is an experiment, my point is that it doesn't suit every use case. Not everyone agrees with the general consensus all the time.
