Spurred on by my recent Lucky7 post on how capital efficient Bazaarvoice was on its path to IPO, two friends sent me great posts this week on entrepreneurship and risk. And I guess it seems appropriate that I'm writing this post from Edinburgh, Scotland here at TED Global. Edinburgh is, after all, one of the birthplaces of capitalism. Adam Smith, author of The Wealth of Nations, and other prominent figures were born here. And speaking of capitalism, the former Prime Minister of Greece and the poster child for the European economic crisis, George Papandreou's, TED Global talk is already live. I found his talk sobering and, for all the controversy surrounding him, it felt rawly authentic to me.
