I love doing traffic tests. This one surprised me. I filtered out surfers by browser language and sent them to a mirror of the exact same site. It was a thumbnail/text TGP. Not all the links on the test site were ran thru the trade script so the productivity is lower than it really is, but for testing purposes the comparison between different languages is dead accurate.

French Canadians clicked more than the chinese, following after the chinese were the Spanish from Peru, followed by Romanians, then Spanish Venezualians, etc
The entire list is here
