The Networks Revolution is in Progress in Mathematics

It's really amazing how quickly the study of networks (and, to a lesser extent, complex systems more generally) --- in contrast to more traditional graph theory --- has gone from being taboo in mathematics departments, which are usually very conservative compared to other subjects, to not only being acceptable and legitimate, but it's now reached the point that any mathematics department that doesn't embrace these topics is simply going to be left behind.

It's been awesome to see this before my very eyes.
