There was initially great hope that the Internet would provide a virtual space where inequalities could dissolve and individuals could interact with others across social, temporal, and spatial boundaries. Decades after the public began using the Internet, we now know that inequalities are easily replicated online. Nonetheless, there are opportunities for decreasing digital divides, such as engaging in various online activities that provide opportunities for enhancing social capital. This study considers the tension between the digital divide nature and the capital-enhancing nature of social networking sites (SNSs). The basic argument is that if (a) there are digital divide differences in use of those different SNSs, then (b) using different SNSs, and (c) using different activities on those SNSs, may foster different potentials for capital enhancement (CE), and (d) purported benefits from social capital, which could (e) reinforce existing inequalities, or (f) reduce the potential for reducing them. This argument is reflected in two primary research questions: First, does usage of SNSs in general and two distinct SNSs in particular reflect basic digital divides? Second, are there subsequent divides in usage of CE SNS activities across these two sites? Digital Divide-Concept and Influences The digital divide is a gap between people (or organizations, social groups, or geopolitical entities) in their communication technology awareness, adoption or ownership, use, and/
