If one assumes that political reform is long, slow, and painful, hierarchies and centralizing strategies can be productive. After all, they can keep the movement on target and give it some coherent shape. Ideas on their own do not change the world; ideas that are coupled with smart institutions might. “Not by memes alone” would be an apt slogan for any contemporary social movement. Alas, this basic insight—that political reform cannot be reduced to the wars of memes and aesthetics alone, even if the Internet offers an effective platform for waging them—has mostly been lost on the Occupy Wall Street crowd.9 Challenging power requires a strategy that in many circumstances might favor centralization. To reject the latter on philosophical grounds rather than strategic grounds—because it is anti-Internet or anti-Wikipedia—borders on the suicidal.
