1. #1 toto

    From the Wikio info page:

      The position of a blog in the Wikio ranking depends on the number and weight of the incoming links from other blogs. Our algorithm accords a greater value to links from blogs placed higher up in the ranking. […]
      Only links found in RSS feeds are counted. Blogrolls are not taken into account.

    So this is basically a measure of how much “buzz” a given blog generates. Which explains why 3 of the top 4 are climate blogs (and why Anthony Watts is #2 while Ed Yong is #15…)
