The annual Skoll World Forum on Social Entrepreneurship, now in its fifth year, is above all a celebration of social entrepreneurship and social entrepreneurs. The annual Skoll Awards are unchallenged Oscars of the field. The recent Forum, held in Oxford, UK at the end of March, was also live testimony to the pulling power – sorry, convening power – of today’s philanthropists, with one ex-US President, one almost President and a clutch of Nobel Laureates heading a glittering array of speakers.
