I can easily see the top 100 sites on Quantcast, or most of their competitors, but they're based on US uniques.Now, Quantcast provides Top Lists for non-US Visitors, but they're country by country, so I'd have to dump the Top list from each country and sum them, which isn't practical.  Is there some other way to get the top X sites based on global uniques?
Is there an easy way to see the Top 100 Global Websites based on monthly uniques?
