Submitted two days ago and was on the front page for over a day:<p><a href="http://news.ycombinator.com/item?id=1499868" rel="nofollow">http://news.ycombinator.com/item?id=1499868</a><p>Many comments and lengthy discussions, some of which were very interesting.<p>Don't comment here - go read that item instead.<p>Ask PG: These URLs seem identical - is the duplicate detection not working at all? What am I missing ...
