The purpose of this book is to discuss the relationship between young people and social networks, focusing on the issue of visibility, social status and the search for belonging. In this way, it analyzes the social and historical reasons why young people share their private lives on social networks. It also aims to understand how these new dynamics of sociability that the internet provides end up interfering in the construction of young people's subjectivity. The techniques used were virtual ethnography and semi-structured interviews. The results were that young people don't post parts of their daily lives for vanity's sake, but also post their daily lives to find other people who have similar likes and thus find belonging in this fluid world that is the Internet.
