Jointly they edit: examining the impact of community identification on political interaction in Wikipedia.

Background: In their 2005 study, Adamic and Glance coined the memorable phrase 'divided they blog', referring to a trend of cyberbalkanization in the political blogosphere, with liberal and conservative blogs tending to link to other blogs with a similar political slant, and not to one another. As political discussion and activity increasingly moves online, the power of framing political discourses is shifting from mass media to social media.

Methodology/principal Findings: Continued examination of political interactions online is critical, and we extend this line of research by examining the activities of political users within the Wikipedia community.
