From a really fascinating article, just one gem:
“Intriguingly, different linguistic communities seem to have very different blogospheric topologies. The English-language blogosphere appears as a knotty, fibrous mesh, while Scandinavian and Japanese blogs map as something more closely resembling a blotchy Jackson Pollock painting. Russian blogs, by contrast, seem to be heavily clustered in dispersed and minimally interconnected wedges.”
As I say, this is just one little bit. Do read the whole thing.
