Despite the overwhelming and unabated popularity of social networks in the past years, the motivation behind an individual’s registration to such platforms is still largely uncharted. Based on an in-depth review of leading Information Systems literature, this paper investigates which factors potentially influence individual´s self-disclosure in social networks. The literature review reveals information privacy violation as the primary risk of online platform use. Regarding benefits, two categories are identified: social benefits, like reciprocity, relationship building and maintenance, or self-presentation as well as non-social benefits related to convenience, like personalization, entertainment, and safety and security. The later ones are mostly neglected in existing models. The main contribution of this paper consists of filling this gap by developing an enhanced research model of the user’s self-disclosure in social networks.
