The value of online friends: Networked resources via social network sites

This study investigated the instrumental value of resources embedded in online social networks. Forty-nine primary participants solicited a total of 588 secondary participants who were asked to complete a modest task. Approximately 16 percent of all secondary participants responded (N=98) to the request. 8.5 percent of weak ties responded and strong ties were about three times more likely to respond. Perceived reciprocity, contact frequency and a composite measure of tie strength were all positively related to enacted support.
