You may be wondering why your comment got down-voted. It's not that we're a community of jerks, I promise. People just really prize a high signal-to-noise ratio here, and while we appreciate that you enjoyed the link, a better way to express that without adding noise is to up-vote the comment.
In general, you should post comments here only when the comment will provide value to someone else. That's largely the rubric by which it will be judged.
