A) cultures are different and such subjective argument is not enough to use down-vote. If you are some smart ass who want something without emotions, go and chat with your PC, but if you are reading public opinions, do not be surprised that they are written by humans (probably containing some emotions). F) when someone makes something good and publishes it to be accessible by society it is normal to receive thanks, especially if it is open source project or non-commercial project aimed to make the world better. But suddenly some smart asses appears from nowhere with zero contribution, but with privilege to make other achievements invisible. In my belief down-voting system is unfair. Especially if you are advised to shut-up when you are down-voted because it makes conversation boring... As HN does not stimulate responsible conversation, but only something like "say and shut-up if we do not like you", there are no reason for me to keep track of conversation and provide more arguments to prove that I am right.
