Query: Diffusion Dynamics with Changing Network Composition   We analyze information diffusion using empirical data that tracks online
communication around two instances of mass political mobilization, including
the year that lapsed in-between the protests. We compare the global properties
of the topological and dynamic networks through which communication took place
as well as local changes in network composition. We show that changes in
network structure underlie aggregated differences on how information diffused:
an increase in network hierarchy is accompanied by a reduction in the average
size of cascades. The increasing hierarchy affects not only the underlying
communication topology but also the more dynamic structure of information
exchange; the increase is especially noticeable amongst certain categories of
nodes (or users). This suggests that the relationship between the structure of
networks and their function in diffusing information is not as straightforward
as some theoretical models of diffusion in networks imply.
