Technically, your comment is also against the HN guidelines. And so is mine (the very one you're reading right now). I think none of us are adding anything to the discussion.
While a comment is, strictly speaking, something submitted, the guidelines page seems to use "submission" to refer specifically to story submissions (note the headers "In Submissions" and "In Comments"). If my interpretation is correct, then my first comment, your reply, and this comment are not in violation, although yours is factually incorrect. :)
Please don't submit comments complaining that a submission is inappropriate for the site.
