At some point, we're going to cut the branding middle-man, and put Bing on the front page of HN as a viable alternative to Google Search. Not as sexy as the high-minded front organizations that reskin it, but it'd be nice if we could be honest with ourselves about the beasts we were feeding.
Also, for the older crowd who came from slashdot (and still says 'Micro$oft') it'd be morally unacceptable to use Bing directly. They prefer either a rebrand, or to directly give all their data to Google (maybe because they still see it as fresh and new?)
So close, but no cigar.
