 These sorts of questions about how online friendships measure up to offline ones, along with questions about whether or to what extent online friendships encroach upon users’ commitments to embodied, ‘real-world’ relations with friends, family members and communities, defined the ethical problem-space of online friendship as SNS began to emerge. But it did not take long for empirical studies of actual SNS usage trends to force a profound rethinking of this problem-space. Within five years of Facebook’s launch, it was evident that a significant majority of SNS users were relying on these sites primarily to maintain and enhance relationships with those with whom they also had a strong offline connection—including close family members, high-school and college friends and co-workers (Ellison, Steinfeld and Lampe 2007; Ito et al. 2009; Smith 2011). Nor are SNS used to facilitate purely online exchanges—many SNS users today rely on the sites’ functionalities to organize everything from cocktail parties to movie nights, outings to athletic or cultural events, family reunions and community meetings. Mobile SNS applications amplify this type of functionality further, by enabling friends to locate one another in their community in real-time, enabling spontaneous meetings at restaurants, bars and shops that would otherwise happen only by coincidence.
