A research project using 'complex networks' analysis to demonstrate the shift from traditional media to networked media in the san francisco bay area. The study examines news-to-news, author-to-link, and commenter networks, and explores effective factors such as density, centrality, betweenness, degree of leakage, and agenda setting.

Predictions
• News-to-news network
– Groups of websites
- Source
- Hubs
- Blogs
– Big organizations have more inbound links
and very few outbound links
– Blog news websites have outbound links
– Comments are under effect of agenda setting
– Degree of leakage toward Wikipedia like websites
I wonder whether
• There are similar values of
– Average number of inbound or outbound links
for the websites in the same category
– Average number of comments etc
• There are popular news, authors, commenters
Problems
• No standard structure of websites
- Author
- Comment
- Commenters
• Old websites have huge amount of pages
- Hard to crawl
- Links to non-existing websites
