6.2 Density And Centralization

The primary measure of community we consider is the density of links between blogs within the community. The greater blogosphere is infinite and the chance of a link decreasing randomly within one of these little communities is insignificant. We find, however, that blogs link on common to one or more other blogs within the community. Blogroll associates are more several than post citations.

Centralization measures the equal opportunity of allocation of links. In all communities, there is better centralization of outdegree , meaning that a small number of blogs have very long blogrolls and/or cite other blogs often, while many list few or no other community blogs in their blogrolls.
