    "abstract": "We develop a new approach to the study of the dynamics of link utilization in\ncomplex networks using records of communication in a large social network.\nCounter to the perspective that nodes have particular roles, we find roles\nchange dramatically from day to day. \"Local hubs\" have a power law degree\ndistribution over time, with no characteristic degree value. Our results imply\na significant reinterpretation of the concept of node centrality in complex\nnetworks, and among other conclusions suggest that interventions targeting hubs\nwill have significantly less effect than previously thought.",
