Building upon the framework presented by David Post – one of the first and most prominent scholars of cyber law and a contributor to this volume – the authors address the implications and economics of the Internet’s astronomical scale, jurisdiction and enforcement of the web as it relates to topics including libel tourism and threats to free speech, and the power of global communication to dissolve and recreate identities.
