Findings--Friends use the city similarly, and you have a higher chance of running into a friend if you live in the suburbs. Method--mapping ellipse-shaped polygons of where people make/receive calls in Jiamusi China, and those of his or her phone call friends. Good for--if you have a geolocated social network and you want to learn more about who uses which parts of the city, and whether the city is set up for friendships.

Findings--Despite a devastating N-S Civil War,  phone calls still connect N-S cities, moreso than E-W cities. Coastal cities host most of the calling. Method--mobile phone call flows from city to city. Good for--understanding a nationwide economic system.
