Those darn bloggers, making the news environment better. I don’t have the full paper handy, but I can link to Serena Carpenter’s abstract:

The presence of a diversity of information offers citizens access to a range of ideas, expertise and topics. In this study, a measure of content diversity was created to determine whether online citizen journalism and online newspaper publications were serving this function in the USA. Based on the findings from a quantitative content analysis (n = 962), online citizen journalism articles were more likely to feature a greater diversity of topics, information from outside sources and multimedia and interactive features. The findings suggest online citizen journalism content adds to the diversity of information available in the marketplace.
