This year’s title (theme) of the Skoll World Forum was “Catalysing Collaboration” and I believe it fully lived up to it. The program reflected and encouraged much more interaction than in previous years. No doubt the OxfordJam programmes running parallel to the forum and the fact that many of us got stranded due to the volcano eruption resulted in further discussions and collaboration. There are many videos and podcasts for anyone who would like to see or hear some sessions. One of the most inspiring speeches was from Caroline Casey delivered at the closing plenary. Blog discussions after the Forum (see socialedge ) are also very interesting to follow. There seems to be an amazing energy and momentum which is expanding the sphere of social entrepreneurship from a “small club of unreasonable people” to mainstream. Perhaps the definition of “social entrepreneur” might not be enough to accomodate the many people that are joining the movement. Call them changemakers (as Bill Drayton refers to them) or maybe a new word like social interpreneurship (see Peter Deitz’s blog): what matters is that with more people trying to make a difference and with more interaction and collaboration there is renewed hope to tackle the enormous problems that society faces today.
