This paper explores the relationship between the use of social media, attitudinal strength, perceived opinion agreement with social ties, and willingness to discuss a political issue in different online and offline contexts. Unlike the anonymous environment of some Internet forums, social media are closely tied to the relationships and activities of everyday life. Social media increasingly make ties from offline contexts persistent online, and, because of the ambient nature of these technologies, awareness of the opinions, interests, and activities of social ties has become pervasive. As such, the use of social media is likely to affect everyday conversation about political issues in on-and offline contexts, including the home, workplace, social gatherings with friends, community meetings, and on social network sites (SNSs). Based on a national probability survey, we find that the use of SNSs (i.e., Facebook and Twitter) has a direct, negative relationship to deliberation in many offline settings. Some uses of these platforms are associated with having a lower, perceived opinion agreement with social ties. As part of a spiral of silence, this further reduces the willingness of social media users to join political conversations in some offline settings. Only those with the strongest attitudes on an issue are immune. ARTICLE HISTORY

This study examines the relationship between mode of Internet access, variety of online activities, and the potential for the Internet to contribute to local social capital in distressed, urban communities. Based on a sample of 525 telephone surveys in Detroit, findings show that breadth of access predicts participation in a larger variety of online activities, which is associated with higher levels of local social capital. Neither public Internet access, home broadband, nor Internet access through a mobile phone data plan alone affords participation in a full range of social capital-enhancing activities. The findings highlight the potential problems of initiatives that assume equivalent social outcomes through nonequivalent modes of access, such as providing Internet access through mobile phones in place of home broadband. Efforts to enhance a city’s social infrastructure by providing Internet access are best served when individuals have multiple points of access available.
