A little dated but still worth knowing, I found this article about a chap - "Matt Cutts works for Google and has a blog about how to court their search engine; so, when Matt flaps his blog wings in America there is a tsunami on the far side of the Internet."

Which alleges that - According to China Internet Network Information Center, CNNIC, Google is losing market share from 33% last year to current 25.3%.

It goes on to support this at the following link @ Linux World .
