It's an idiosyncrasy of the site that we avoid highlighting things in titles ("stories are community property, and submitting one doesn't give anyone the right to editorialize them").

I agree that the title we ended up with is suboptimal! "Exploitable" is a word I'd have been comfortable seeing there. But you take the good with the bad with the HN title rule; the site is primarily about discussion, not about being a noticeboard, and titles determine the discussion we have.
