The Guardian released a list of the 50 most powerful blogs. Many are not surprising, but it includes some interesting choices, especially in the top 10:

Boing Boing — certainly a powerful blog, but I’d be surprised if it’s the second most powerful in the world.

Dooce — once fired for blogging, she now writes mostly about her preschooler or her dogs, with the occasional bit about Utah. It’s certainly popular.

Icanhascheezburger — behold the power of the LOLcat.

There are also some interesting omissions, like, say, Daily Kos, Fark, and Feministing.
