Into the Blogosphere

Abstract:

Maps of any aspect of the Internet call for different approaches than traditional cartography for two reasons. First, any attempt to map the Internet using the Internet as a medium changes the thing it sets out to represent. Second, Internet maps are more than pictures of static—or at least relatively slow moving—features but are representations of ever changing systems of relationships. The blogosphere is an example of explosive growth in the number and complexity of interrelationship and community made possible by the Internet.
