Social networks that matter: Exploring the role of political discussion for online political participation

We examine the relationship between citizen-to-citizen discussions and online political participation considering various attributes of individuals' social networks: Modality, discussants' ties, diversity of opinions, and quality of argumentation. Using a national survey of U.S. residents we find that communication within networks is a significant predictor of web-based forms of political engagement, after controlling for offline participation, political orientations, news use, and socio-demographics. Consistent with the "strength of weak ties" argument, larger online networks and weak-tie discussion frequency are associated with online participation. While like-minded discussions are positively related to online participation, discussions with people who are not of like mind correlate negatively with it. Online network size and reasoning discussions were positively related to online participation, although these associations were rather weak compared to the role of other network characteristics.
