How do you do this?

Is there a way to find the most trafficed sites by extension?

For instance, is it possible to find which .org sites get the most traffic?

I would take the 1-mil. Top Alexa and 1-mil Top quantcast lists (recently made avilable for free)

Thanks Denny.

Any other methods, or tools to run a quick check?
