The roles of media capabilities of smartphone-based SNS in developing social capital

Smartphone-based social networking service (SNS) is widely used as a key social platform that promotes users to build and maintain interpersonal relationships. However, little is known about the main characteristics of smartphone-based SNS that strengthen social relationships. By combining studies of mediated-communication namely, media richness and social presence with the social capital theory, this study proposes that the advanced media capabilities of smartphone-based SNS enable users to develop bridging and bonding social capital. Moreover, the study suggests that advanced media richness increases social presence referring to the feeling of being connected with others in virtual environments. As a key outcome of social capital in the context of smartphone-based SNS use, user satisfaction is considered. The results indicate that first, media richness and social presence, which represent media capabilities of smartphone-based SNS, greatly increase bridging and bonding social capital. Second, media richness enhances social presence in the context of smartphone-based SNS use. Finally, bridging and bonding social capital are key determinants of user satisfaction with smartphone-based SNS. Discussion and implications on the results are presented.
