The document discusses strategies for creating and maintaining engaged communities on social media. It recommends appointing a community manager, determining how consumers want to engage, and making a long-term commitment of people, money, and resources. Campaigns can then be run to encourage sharing and invite new members, as long as they align with the community's terms. Successful campaigns may be integrated into ongoing community activities, while others will finish as planned. An engaged community allows brands to introduce better-informed campaigns.
