This chapter examines cyber-speech and its implications for free expression. It first provides an overview of the technologies involved, from simple systems such as web pages, blogs, and internet fora to social media platforms (SMPs), and media-sharing sites. The chapter then highlights the social implications of the shift in power from centralized media organizations to users. It also considers the responsibilities that users owe to each other in this environment and how regulators may balance freedom of expression with social responsibility. To determine whose values predominate when regulating a global media tool which does not recognize traditional borders, the chapter presents two case studies: political speech and hate speech.
