"Trebor Scholz and Laura Y. Liu reflect on the relationship between labor and technology in urban space where communication, attention, and physical movement generate financial value for a small number of private stakeholders. Online and off, Internet users are increasingly wielded as a resource for economic amelioration, for private capture, and the channels of communication are becoming increasingly inscrutable. Liu and Scholz ask: How does the intertwining of labor and play complicate our understanding of exploitation?"--Publisher's Web site.
