Conversations in the Blogosphere: An Analysis "From the Bottom Up"

"The "blogosphere" has been claimed to be a densely interconnected
conversation, with bloggers linking to other
bloggers, referring to them in their entries, and posting
comments on each other's blogs. Most such characterizations
have privileged a subset of popular blogs, known as
the 'A-list.' This study empirically investigates the extent
to which, and in what patterns, blogs are interconnected,
taking as its point of departure randomly-selected blogs.
Quantitative social network analysis, visualization of link
patterns, and qualitative analysis of references and
comments in pairs of reciprocally-linked blogs show that
A-list blogs are overrepresented and central in the
network, although other groupings of blogs are more
densely interconnected. At the same time, a majority of
blogs link sparsely or not at all to other blogs in the sample,
suggesting that the blogosphere is partially interconnected
and sporadically conversational."
