Using time series analysis to gauge intermedia agenda setting in a sample of eighteen U.S. political blogs, two elite traditional news entities, and their eleven political newsroom blogs across three issues in 2007, this study reveals that traditional media were unable to set political blog agendas. Ideologically diverse political blog networks were also able to set traditional media's online news agenda, and, to a lesser extent, their newsroom blog agenda. Findings point to a dilution of traditional media's singular agenda-setting influence and to greater interdependence between traditional media and political blogs than suggested by hyperlink studies.

This study examined whether information about a writer and hyperlinks on a citizen journalism Web site affected the perceived credibility of stories. Participants read stories from a popular citizen journalism Web site and rated the stories in terms of perceived credibility. Results show that hyperlinks and information about the writer do enhance perceived story credibility. Credibility is enhanced most greatly when both hyperlink and writer information are included and, to a lesser extent, when just hyperlink or writer information is present. [ABSTRACT FROM AUTHOR]
