Observer Publishes 50 Most Powerful Blogs But ...

OK, so they've got Techcrunch, Kottke, Engadget, Boing Boing, Gaping Void and Chocolate and Zucchini but I can't see how some of the others rank in the listing of 50 Most Powerful Blogs. There is no Seth Godin, Steve Rubel, Search Engine Land, Google Blog, Matt Cutts, Slashdot, Lifehacker or Guy Kawasaki. All of the latter are the really powerful blogs which have a much bigger influence on their own sphere of business.
