An examination of the Technorati rankings for recent years reveals that turnover among the top 50 blogs has become increasingly rare. Even as the total number of blogs has swelled to 133 million from 27 million in 2006, the top 50 have remained relatively static. On March 15, 2006, 30 blogs out of the top 50 were new to the list, never having appeared at the top in any previous year; last month, that number was down to 18.
Of the top 50 blogs, 21 are owned by such familiar names as CNN, the New York Times, ABC, and AOL.
An immense proportion of the online readership—roughly 42% of all blog traffic—flows to the top 50 blogs.
What do you think? Is the "democratic" nature of the blogosphere being bought up by titans?
