That Max Berger has some real zingers. He and I spent the past few days at Harvard with Marshall Ganz and the Leading Change Network. Max discussed Occupy Wall Street during a panel on Organizing vs. Mobilizing. And — boom — he drops this ripe physics metaphor: Force equals mass times acceleration. We [Occupy Wall Street] had a lot of acceleration and little mass. Preach it, comrade Berger. Can you spot the real Max Berger?
