80% of A-list Blogs Originate from the US

As part of our Ads On Blogs 500 analysis of the Feedster 500 we looked at the international composition of blogs. As with other parts of our research the observation analysis was difficult and in this instance we were only able to substantiate the ownership of 329 blogs out of the 500. Our percentages are therefore based off only the identifiable 329 and not the entire 500. Nonetheless, this should give a useful indication of international composition even if it is limited by those sites operating in English.
