Book excerpt: Social media enables instant access to individual self-expression and the sharing of information. Social media issues are boundless, permeating distinct legal disciplines. The law has struggled to adapt and for good reason: how does the law regulate this medium over the public/private law divide? This book engages with the legal implications of social media from public and private law perspectives and outlines how the law, in various legal sub-disciplines and with varying success, has endeavoured to adapt existing tools to social media.
