Whenever I encounter a rhetorical question in a headline or link, I assume the author is either going to reach some foregone and facile answer, or no answer at all.<p>In this sense, questions as headlines are not only linkbait; they're often the signs of worthless articles, usually consisting of regurgitated common sense, or else poorly distilled coverage of superior source material.<p>There are occasional exceptions, to be sure. But generally, if I can guess what answer an author is going to get to long before he gets there, he's wasting my time.
