The L.A. Times did a story on Saturday about the website www.talkingpointsmemo.com which is owned and operated by Josh Marshall. The article, which you can read by clicking on the link in this entry's title, is a very interesting analysis of the advantages and disadvantages of blogging using Marshall's pushing of the fired U.S. Attorneys as a case study.
One thing that the article makes clear is that blogging has a much closer relationship with its readers than mainstream journalism. The article also quotes the founder of company selling blog ad space as claiming that left of center blogs are getting over 160 million page views per month. If that is based just on the blogs that are running ads from his company, then that means that there are many more page views on left of center sites that are not being counted. This blog, for example, does not run any ads and so would not be counted in his research. Check out the article, we think you will find it interesting.
