Directed network of 85,013 nodes and 129,079 edges
[ 73% of blogs in the largest connected component ]
Average node degree 1.5
Power-law degree distribution
6% of links are reciprocal
35% of links cross blog domains
7% of links cross language boundaries
Network structure is more sparse than social networks
Density = Ratio of observed links, out of all possible links
Popular sharing of user-generated content
We downloaded metadata of top 10,000 videos
Blogs linking the same video are connected
= Diffusion through the blogosphere
