Hi,
I work at StatCounter and I would just like to point out that we have a very diverse sample size from around the world.
As per http://gs.statcounter.com/faq#sample-size for July 2009 here was the breakdown of our sample pageviews for the month.
* 1.3 billion United States
* 570 million Brazil
* 280 million Turkey
* 260 million Germany
* 250 million Thailand
* 240 million China
* 240 million United Kingdom
* 180 million Indonesia
* 160 million Canada
* 140 million India
* 109 million Russia
I'm from StatCounter and I would just like to address your concern. The detection for baidu was added on the 5th March 2009 at 21.00 GMT. When a new detection is added it is noted on the visual graph (but not in the csv download).
Also if you look at the stats just for China you can easily see Baidu's dominance there.
