The political blogosphere has recently been the focus of attention for social network analysis and applications of network and graph theory. In a recent paper, Adamic and Glance (2005) report differences between the linking behavior of politically conservative vs. politically liberal Web bloggers. We construct a simple agent-based network formation model which shows that one such difference, demonstrating what we term 'political homophily', can be generated by connecting the blogosphere to the underlying population distribution of political preferences. The model is implemented as a web service in the e-tool VOSON (Virtual Observatory for the Study of Online Networks), and both model and tool serve to define a natural environment for research into link formation behavior with large numbers of heterogeneous network participants.
