The totalizing scope of the combined effects of computerization and the worldwide network are the subject of the essays in The Digital Nexus, a volume that responds to McLuhan’s request for a “special study” of the tsunami-like transformation of the communication landscape. These critical excursions provide analysis of and insight into the way new media technologies change the workings of social engagement for personal expression, social interaction, and political engagement. The contributors investigate the terms and conditions under which our digital society is unfolding and provide compelling arguments for the need to develop an accurate grasp of the architecture of the Web and the challenges that ubiquitous connectivity undoubtedly delivers to both public and private life.
