No longer the exclusive domain of the wealthy, the specialist, or the enthusiast, today the internet is available to almost anyone who desires to use it and has become an integral part of our everyday world. The essays in this volume examine the effect of the online environment on our social lives via three analytical frameworks: fit, link, and position. They address the way in which the Internet has become an entrenched part of our personal and professional world and a vital tool on which we are increasingly dependent. The volume also explores the capacity of the Internet to embody our economic, cultural, and political 'position' online.
