This document summarizes research on user-generated content and citizen journalism. It discusses how user-generated content has long been central to community media. It reviews previous research on whether community media "mattered" and if it gave citizens a voice. It argues this research missed how community media has changed in the digital age. It provides the example of OhmyNews, a site where citizens and journalists collaborate to provide news. It suggests more study is needed on how such collaboration between citizens and journalists can flourish.
