One of my least favorite activities of all time is the icebreaker. You know how it goes: Throw together a bunch of people--six, eight, more than two is too many--and force them to tell each other something silly, secret, anything that will publicly humiliate in front of total strangers. Cue nervous laughter and clammy palms. But barely has the Skoll World Forum for Social Entrepreneurship begun and Ideo is already telling us: We have a better way. We're going to use design.
