Whenever I see an article that has much lower upvotes than comments I wonder why HN doesn't just automatically upvote an article when someone makes an initial comment (if they haven't already upvoted the article). If you are interested enough to post a comment then you probably should upvote the article, even if you don't agree with it. Why? Because it's likely generating a good and interesting discussion. This article is a great example of this phenomenon.
