Collapse of an Online Social Network: Shall We Blame Social Capital?

László Lőrincz, Anna Fruzsina Győr, Júlia Koltai, Károly Takács

Abstract: The rise and popularity of online social networks is a recent phenomenon. In this study, we analyze the reasons and mechanisms behind the collapse of an online social network (OSN), iWiW. Significant cascading mechanisms have been identified in the pattern of abandoning the site at its peak of popularity and after. We analyze individual and structural mechanisms that triggered users to abandon the site early in their network, starting a cascade. We contrasted explanations based on preserving accumulated or building new social capital with motives governed by innovativeness for abandoning the site early. On the one hand, those who are well embedded in their existing network have more to lose. We find with heterogeneous choice models that lower degree is associated with early abandonment. On the other hand, people might want to escape from redundancy and indebtedness indicated by a high local clustering coefficient. This is confirmed in our analysis in addition to the effect of degree. The significant effects of innovativeness and age indicate that not only social capital should be blamed for the collapse of the OSN.
