Scott Wilder discusses how to build a marketing nation by mobilizing communities. He outlines 10 steps to do so: 1) gain organizational commitment, 2) use an evolutionary process, 3) build infrastructure, 4) operationalize processes, 5) accept that ebbs and flows will exist, 6) pick the right tools, 7) understand different tribes within the community, 8) build a virtual watercooler for people to connect, 9) empower community members to spread the word, and 10) leverage data. The key is activating the existing marketing nation by bringing people together around a shared purpose.
