Juris gives us an excellent ethnographic study of networked social movements, without losing site of his subject.
Many recent monographs that take as their object of interest "networks" or "social movements"-- shifting and somewhat ephemeral as they are-- jump around too much in their attempts to "follow the object." These examples tend to be overly theoretical and devoid of the best qualities of ethnography: human voices!
Juris manages to follow his interlocutors around the globe to different anti-globalization protests, rallies, etc, while still giving ethnographic insight into who these people are, what their motivations are, and how they manage to organize their groups across geographic and digital space. Juris's "militant" positioning allows him to get inside information from radical anarchist groups while being critically reflexive.
Juris's book struck me as an innovative approach to studying social movements. An important and interesting topic given the influence of various social movements and interest groups on politics today. I would really like to see it compared to a similar type of study on right-wing political movements.
