There is a general perception that synchronous, online chat about politics is fragmented, incoherent, and rife with ad hominem attacks because of its channel characteristics. This study aims to better understand the relative impact of channel of communication versus topic of communication by comparing chat about four different topics. Discourse analysis and coding for topic drift were applied to two hours of chat devoted to the topics of politics, auto racing, entertainment, and cancer support. Findings demonstrate that topic may have an effect on the coherence of chat, with discussion in the politics chat room surprisingly being more coherent than in the other rooms. This research suggests that users can sustain relatively coherent interaction on political talk, suggesting chat technology may not be an inherently problematic medium for political discourse.

ABSTRACT
This study examines if Facebook, one of the most popular social network sites among college students in the U.S., is related to attitudes and behaviors that enhance individuals' social capital. Using data from a random web survey of college students across Texas (n = 2,603), we find positive relationships between intensity of Facebook use and students' life satisfaction, social trust, civic engagement, and political participation. While these findings should ease the concerns of those who fear that Facebook has mostly negative effects on young adults, the positive and significant associations between Facebook variables and social capital were small, suggesting that online social networks are not the most effective solution for youth disengagement from civic duty and democracy.
