here's why i think it's clever.<p>there are certain evergreen topics here that are always going to lead to heated debate. iphone versus android versus pre, mac versus windows versus linux, rails versus drupal versus php, ruby versus python versus c++ versus perl versus lisp, etc etc etc.<p>each time an article is posted here that takes a stand one way or the other, it prejudices the resultant discussion. it's sort of inherently understood that, if you want to comment strongly anti-iphone, you better wait until the posted article itself is also anti-iphone, or else you're going to face stiff opposition and downvotes.<p>by posting two articles, one pro-tab and one anti-tab, the submitter has neatly sidestepped that problem. if news.yc tilted strongly one way or the other, you'd expect one article or the other to get most of the upvotes, and the other one would sink. as it turns out, both articles have been running neck-and-neck for hours. interesting. it shows that tab lovers and haters exist here in equal proportions, which i really wouldn't have guessed.
