When I look at the Google Trends for "golang", China is the top region by a huge margin (the next highest region after China is Sweden at 30) [ http://i.imgur.com/XHW40kp.png ].
And the rise of interest in "golang" in general seems to correspond to the massive spike in China [ http://i.imgur.com/Y3oO2jf.png ].
I'm not really sure what that means...
