I found out about the AdAge Power150 which ranks the top marketing blogs worldwide (English language though) in January and annoyed that Bannerblog wasn't listed. After a quick email we are now on the list but at a dismal rank of 165. Which I'm told is down 107 from the day before? Our stocks going terrible too :)
Update: Ok this list automatically updates and we're now ranked a respectable 60. I now have another stat to check everyday.

The top blogs are an interesting mix with Seth Godin's blog taking top spot. Which is what you'd expect from a celebrity with a book publishing career. I have two of his books myself.
