Spawn

On July 6, Rockefeller created a Facebook group called Buy Nothing Bainbridge and added Clark as a co-administrator. By the end of the day it had more than 100 members. Within weeks the group had added hundreds more members, and strangers in nearby towns were asking how they could start their own. Rockefeller and Clark helped them, and by the end of December they had created 78 Buy Nothing groups, with more than 12,000 members in all.

The day before New Year’s Eve, Clark, Rockefeller, and a group of friends and Buy Nothing members got together to plan for the future. They had tea and muffins, then did an exercise. On multicolored index cards, they each wrote down their wildest dreams for Buy Nothing. One woman hoped that it would become a nonprofit and publish a magazine; another imagined it would spawn a virtual currency.
