In this Chapter we will introduce different perspectives on scale in the Slow Lane. We will start by using scale as a noun, sizing up the Slow Lane itself. After consulting experts in the field of social change I came to estimate that there are about 50,000 communities like User Voice in the Slow Lane. But it turns out to be much bigger. A fresh look at data showed that a billion people may be contributing to more than fifty million Slow Lane communities already.
