Book excerpt: Inspired by the “technologies of the self” theorized by Michel Foucault in the early 1980s, this volume investigates how contemporary individuals fashion their identity/identities using digital technologies such as ambient intelligent devices, social networking platforms and online communities (Facebook, CouchSurfing and craigslist), online gaming (SilkRoad Online, Oblivion and World of Warcraft), podcasts, etc. With high-speed internet access, ubiquitous computing and generous storage capacity, the opportunities for staging and transforming the self/selves have become nearly limitless. This book explores how technologies contribute to the expression, (co-)construction and enactment of identities. It examines these issues from various perspectives as it brings together insights from different disciplines – design, discourse analysis, philosophy and sociology.
