David Rostan, Founder of Social Yell, explains how his site allows consumers to rate the social responsibility of companies. The site allows for two-way conversations between users and the companies they rate. They use Twitter to illicit requests for features and get feedback on how they are doing. They are also seeking out conversations about companies' social responsibility on Twitter and encouraging them to share their thoughts and feelings using Social Yell. Social Yell is on Twitter at http://twitter.com/socialyell and on the web at http://socialyell.com
