Although increasingly enabled by technology, monitoring and tracking is not a new addition to the range of human social activities. Nor is it necessarily mediated, as there are countless mundane ways in which people are tracked and monitored: teachers take attendance, parents watch toddlers in a park, and coaches keep track of athletes' performance. Further, although privacy concerns accompany many contemporary monitoring and tracking practices, this does not necessarily need to be a factor, as when physicians monitor the heart rates of their patients or Olympic judges scrutinize and evaluate athletes' routines.

Not only is there an increase in sheer frequency of technology-mediated monitoring and tracking but a resulting shift in its nature—automated, undiscriminating, and accommodating new subjects, monitors, and motives. Following at the heels of these changes, there is growing discomfort, suspicion, and perplexity. In this chapter a variety
