This article discusses practices of self-exposure on social networks. In the last decade, much research has discussed, directly or indirectly, the phenomenon of digital visibility. It appears essential, or at least relevant, to initiate this heuristic approach and to review the results that have been made on the subject. The expansion of information and communication technologies has changed traditional forms of social interaction, inducing a reassessment of digital self-exposure and a development of regulatory practices of this mode of information dispersion. Therefore, we propose to reconsider the various works that have improved our understanding of this research subject.
