Good thoughts, and good idea at the end. I'll likely run some different adverts and see which ones produce the best revenue for each country/browser/OS etc. eastern-europe: opera=8% usage, compared with US: opera=2% usage So you may have a point there - Opera users are less likely to be in easy-to-monetize countries. In terms of absolute numbers, there's more Opera users outside the US/EU, than inside.
