Analysis of the statistics blogosphere by John Johnson.
From the post:
My analysis of the statistics blogosphere for the Coursera Social Networking Analysis class is up. The Python code and the data are up at my github repository. Enjoy!
Included are most of the Python code I used to obtain blog content, some of my attempts to automate the building of the network (I ended up using a manual process in the end), and my analysis. I also included the data. (You can probably see some of your own content.)
Excellent post on mining blog content.
A rich source of data for a topic map on the subject of your dreams.
