What is it about?
By shrewdly picking people based on their structural location within face-to-face social networks (i.e., who they know and who their friends know), it is possible to more rapidly and completely induce update of desirable public health interventions. For instance, we can get more people to use iron-fortified salt in urban India, for example, thereby reducing anemia in mothers and infants.
