From Prof Philip Auerswaldand Mr Iqbal Quadir.

Sir, John Gapper's column "Anyone can become the CEO of You Inc" (January 22) relating to the "Shifting Power Equation" under discussion at Davos focuses on the newly distributed power to achieve celebrity. Potentially more interesting is the newly distributed power to create change. Along these lines, the event of the week may have been the 2007 Schwab Social Entrepreneurs Summit that just concluded in Zurich.
