Communications and personal information posted online are accessible to many, leading to concerns about privacy. Users often share personal data on social networks and blogs, expecting their privacy to remain intact, despite the risks of their information being mined by advertisers or stalkers. The chapters compiled by Trepte and Reinecke delve into this privacy paradox, featuring contributions from researchers in psychology, communication, sociology, and information science. They present new theoretical models addressing online intimacy and public accessibility, along with innovative ideas regarding online privacy. The authors explore how users often sacrifice privacy to enhance social capital and gain various benefits, emphasizing trust and authenticity in social network usage. They analyze how privacy needs shape users' virtual identities and discuss ethical considerations, gratifications, and concerns surrounding online privacy. The volume examines the privacy behaviors of diverse social media users, including young adults and older individuals, and considers privacy in relation to specific online services like social networks, mobile internet, and blogs. Overall, this work provides a comprehensive, up-to-date examination of online privacy and the social web, while also offering insights into future challenges and research directions in the evolving landscape of social technologies.
