Personally I feel, when an article gets a response in the form of a well thought out comment, that the content is relatable and has value to a reader. Even more so when the comments lead to an informative debate on the original content. These comments have just as much intellectual and informative value as the original content and deserve the same upvote as the main article. Comments like "LOL", "nice" "wow" just don't have any value and deserves less of an upvote... Just my humble opinion. (See... your post meant something to me and that is way I bothered commenting)
