A locality model of the evolution of blog networks

In this paper, we present a novel model for the evolution dynamics of social networks which supports public communication (communication which is visible to all members of the network). Though our model is general, it is particularly applicable to blog-networks, which is the domain we use for testing. We use a directed graph, the blogograph, to represent the communication activity in the Blogosphere. Our model is based on three fundamental principles for describing evolution dynamics in social networks.
