If you’re interested in the month’s top 500 blogs then check out Feedster’s list (click here) Each month they list 500 ‘interesting and important’ blogs. It’s based on how many hits a blog gets.
To be honest though I think I agree with Robert Scoble, the writer of the blog Scobeleizer, #74 this month (click here for his blog), “I’m far more honored by having people say “you’re interesting enough to read day after day.”
