Today I'll discuss the impact of weblogs on mainstream media, the impact of the A-List, and the power of the long tail. You can compare today's report with the one in March 2005 and October 2005.

First off, some terminology and an understanding of what we're measuring. The chart below illustrates a measure of influence or authority of a site or blog as measured by the number of people who are linking to it. Note that this is not a measure of page views or website "hits". Rather, Technorati looks at linking behavior as a proxy for attention and influence. In other words, the more people who link to a site or blog, the more influence it has on others.

As the chart above shows, the most influential media sites on the web are still well-funded mainstream media sites, like The New York Times, The Washington Post, and CNN. However, a lot of bloggers are achieving a significant amount of attention and influence. Blogs like bOingbOing, Daily Kos, and Instapundit are highly influential, especially among technology and political thought leaders, and sites like Gizmodo and Engadget are seeing as much influence as mainstream media sites like the LA Times. A note on counting: Some organizations with multiple domains or highly syndicated strategies like the Associated Press and Reuters, are underrepresented in this chart, given that their impact is not easily countable using our methods. An interesting statistic to note is the current placement of subscription sites like WSJ.com (the Wall Street Journal). While the WSJ has begun to offer some content outside of its subscriber-only site, the policy is clearly costing them some influence and attention in the blogosphere, as bloggers find it difficult to link to articles in the subscriber-only sections. Also interesting to note is that even though The New York Times and The Washington Post require free registration to view the articles, bloggers are still linking to the stories, and this behavior hasn't changed much in the past 6 months.

More to come later in the week, including all of the underlying data...
