Yikes. The person of the decade is either George W. Bush or Osama bin Laden. So says the The Washington Post, whose editors have created a march-madness style bracket to determine the most influential person of the 2000s, replete with live interviews, discussion groups, and an interactive bracket (like the picture here, but larger). On December 21, voters will decide between finalists Batman and the Joker Bush and bin Laden.The original list of 16 candidates is as follows: George W. Bush, Timothy Geithner, Lance Armstrong, Paris Hilton, Dick Cheney, Ben Bernanke, Larry Page and Sergey Brin (one entry), Hillary Clinton, Barack Obama, Hu Jintao, Steve Jobs, Jon Stewart, Osama bin Laden, Mark Zuckerburg, Al Gore, and J.K. Rowling. It's kind of an awesome list. Kind of.Via Yglesias, whose post offers the poignant (if playfully reductive) rejoinder that, although this bracket reveals the 2000s to be a pretty lousy decade for Americans, 43 percent of the world's population (the inhabitants of India, China, Indonesia, and Brazil) had a very good decade.
