Supporting Idea
A key point is given by Adrienne Russell to support the idea of new networked media and its reliance in her book
Treatments of new media in Iraq War (2003)
Treatments of old media in Gulf War (1991)
It is referred overtly that George W. Bush was not able to repeat the father Bush’s trick of massaging the message, 12 years after Bush senior expelled Iraqi forces from Kuwait.

Effective Factors• Measure density, centrality, betweenness etc. metrics
• Seek for “degree of leakage”• The links which are not in the ecology
• Influence of “agenda setting”• The power of media in affecting audiences in terms of
• what stories to consider newsworthy • how much prominence and space to give them

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
• Advertisements• Media objects

Related Work• Power-law distribution in co-authorship by Newman• The Internet is slowly closing in on television as Americans’
main source of national and international news
