The conversation about the Web and social media skews toward a discussion of the potential for connections, and how both individuals and organizations are using the media to communicate, to form communities, and to conduct business. Lacking, for the most part, is an investigation of the design of these spaces and how design, both good and bad, encourages or provokes certain kinds of interactions. In her new book, The Social Machine: Designs for Living Online (MIT Press, 2014), Judith Donath, Faculty Fellow at Harvard University’s Berkman Center, explores the theory and practice of interface design, and analyzes how design influences online interaction. With a view toward inspiring designers, and others, “to be more radical and thoughtful in their creations,” Donath provides a detailed examination of topics to be considered for beneficial design.
