Hi All, I'm starting a lit review for an upcoming research project, and I'm looking for work related to 4 mechanisms: 1. What factors contribute to the general population's awareness of Wikipedia? 2. What factors contribute to growth in Wikipedia's readership? 3. What factors contribute to editor population growth? 4. What factors contribute to increased volume and quality of Wikipedia's content? Any pointers towards relevant papers (especially existing lit reviews since this is 4 large areas of research!) would be appreciated. Cheers, Jim
