I think that the content is at least a constructive contribution, even though I'm not sure that I agree with it; but is anything useful really conveyed by the '-1' at the beginning? (I don't know how voting works, but I doubt that "Tell HN" posts by admins are materially affected by up- or down-votes; but, even if they are, what's the point of advertising, rather than just explaining, your vote?)
