It's just normal human nature and a desire of wanting to communicate with others. On the internet comments are the mean of communication as part of an online community. That is no different to talking to a bunch of friends in the pub. It's like asking "why do people talk to each other in a pub. Most conversations in pubs will not be heard by almost everybody in the world. Conversations with one person are only ever heard by one person, so what's the point of talking to them and expressing your thoughts and opinions?" Do you see what I mean? There is no point in the same sense as there is no point in life if that is what you think.
