From chapter: 9 Building a community, not a following, pp. 143–164
A following is a group you talk at and a community is a group you talk with. A community needs only a common interest and a common platform, can start with five or 100 people, and its superfans become advocates who refer you, which is the real goal: become the most referred person in your industry. Sordell covers emotion before logic, an engagement rate, responding to everyone yourself, involving the community in decisions, giving back through micro-versions of paid work, and mirroring the community as it changes. A long before-and-after example shows her tone moving from aggressive to open as her audience and confidence grew.
