There has been debate whether Google search results can remain neutral because of possible conflict of interest. According to Danny Sullivan, the editor of "Search Engine Land", "Google’s goal of making Knol pages easy to find on search engines could conflict with its need to remain unbiased." Jeff Chester, executive director of the Center for Digital Democracy, raised similar concerns: "At the end of the day, there's a fundamental conflict between the business Google is in and its social goals. What you're seeing here, slowly, is Google embracing an advertising-driven model, in which money will have a greater impact on what people have ready access to."
