There is a thread at SEO Chat and there was a thread at SEW Forums that was on this topic but I had to pull it temporarily. But if you search on SEO at Google, you will notice that is overwhelmed with Asian results. At the top of the results it says "Tip: Search for English results only. You can specify your search language in Preferences" But why is Google doing this? Are they having fun with English based SEOs or is it a relevancy thing?
