When historians look back to the moment when the post-Cold War reign of American power ended, they may well settle on 2010 as a crucial year. Everywhere, it seemed, there were signs that the long-predicted "rise of the rest" had finally occurred, whether in the newfound assertiveness of fast-growing China or the impatient diplomacy of new powers like Brazil and Turkey. Foreign Policy's second annual list of the Top 100 Global Thinkers fully reflects that new world. Beginning with Warren Buffett and Bill Gates (1), who teamed up to prove that even in tough times great new ideas can emerge, to forecasting economist Nouriel Roubini (12) to political leaders Barack Obama (3) and Angela Merkel (10), FP presents more than just their big ideas. Once again we took a unique survey of this very smart crowd. Nearly two-thirds participated to give you insight into their thinking on everything from how Obama's doing to their preference in new-age reading device (iPad, by a lot). But don't take our word for it -- take the same questionnaire we sent to our FP 100 and see how your answers match up against theirs.
