Social network site (SNS) use has been very integrated into our daily practices. The distinctions between offline and online social relationship management become blurred with the mediation of SNSs. We are interested in how people perceive and use SNS and engage in social relationship management, such as self-disclosure or privacy management. Users may appropriate technological features to meet their own needs and such practices may be different from how others use the sites. The discrepancy of usage may in turn influence social relationship maintenance.
