摘 要：A growing body of literature and inspirational examples provides guidance for aspiring social media community leaders. We know that design principles for websites can make a substantial difference in getting first-time users to return and to trust commercial, academic, government, and other websites. By contrast, building credible social media communities requires large numbers of regular content contributors guided by inspirational and committed leaders. This paper offers a defining framework for discussing the social, technical, and content foundations that encourage trusted contributors to contribute credible content to social media communities. Each component of the framework -- the trusted contributors, credible content, reliable resources, and responsible organizations -- can be undermined.
