Excerpts from the Introduction:

This is a book about how the free flow of information on the Internet can make us less free. We live in an age drenched in data, and the implications are both wonderful and terrifying. The Internet places a seemingly endless library in our homes; it allows us to communicate with others instantly; and it enables us to spread information with an efficiency and power that humankind has never before witnessed. The free flow of information on the Internet provides wondrous new opportunities for people to express themselves and communicate.

But there's a dark side. As social reputation–shaping practices such as gossip and shaming migrate to the Internet, they are being transformed in significant ways. Information that was once scattered, forgettable, and localized is becoming permanent and searchable. Ironically, the free flow of information threatens to undermine our freedom in the future.

These transformations pose threats to people's control over their reputations and their ability to be who they want to be. Will we enslave ourselves by making it impossible to escape from the shackles of our past and from the stain of gossip and false rumors? How much information should we know about each other? How do we allow people to control their personal information without curtailing free speech or stifling freedom on the Internet?

This book will take a journey through the ways in which private lives are being exposed online, and it will examine the implications. People have profound new ways to communicate, yet the gossip, shaming, and rumors that are being spread online are sometimes having devastating effects on people's lives. Should we do something to stop the exposure of private secrets on the Internet? Can we do anything? In this book I will propose a framework for how we can address these problems—by recognizing a new and broader notion of privacy and by reaching a better balance between privacy and free speech.
