Teknoids

The past decade has seen a convergence of social and technological networks, with systems such as the World Wide Web characterized by the interplay between rich information content, the millions of individuals and organizations who create it, and the technology that supports it. This course covers recent research on the structure and analysis of such networks, and on models that abstract their basic properties. Topics include combinatorial and probabilistic techniques for link analysis, centralized and decentralized search algorithms, network models based on random graphs, and connections with work in the social sciences.

The Structure of Information Networks (Jon Kleinberg)

Just following along with the reading for this course would be interesting.  Most of the stuff is on the net, but you could certainly get your hands on the rest through any university library.
