J-Lab has come out with a study called “New Voices: What Works.” It found that citizen journalism outfits have such high turnover rates that it is inefficient to train classes of citizen journalists. It’s difficult to cultivate a steady stable of journalists in such enterprises because people are busy. Very few citizen journalists do this full time.
It also found that citizen journalism didn’t necessarily dig up stories that were being suppressed by traditional media but rather enhanced the coverage of stories by mainstream media. An example that comes to mind is the video and photo content provided by citizen journalists during the New York tornado.
Jan Schaffer of J-Lab gives a good quick rundown of the publication.
