Abstract: In this paper, we study the linking patterns and discussion topics of political bloggers.
Our aim is to measure the degree of interaction between liberal and conservative blogs, and
to uncover any differences in the structure of the two communities. Specifically, we analyze
the posts of 40 “A-list” blogs over the period of two months preceding the U.S. Presidential
Election of 2004, to study how often they referred to one another and to quantify the overlap in
the topics they discussed, both within the liberal and conservative communities, and also across
communities. We also study a single day snapshot of over 1,000 political blogs. This snapshot
captures blogrolls (the list of links to other blogs frequently found in sidebars), and presents
a more static picture of a broader blogosphere. Most significantly, we find differences in the
behavior of liberal and conservative blogs, with conservative blogs linking to each other more
frequently and in a denser pattern.
