Darkness reigns

Many of you may already be familiar with this image that shows what the Earth looks like at night with no cloud cover... and specifically the darkness that is North Korea and the lack of development/connectivity that represents:

Well, here's another one that's kinda similar that you might not be quite as familiar with.  It maps out the connectivity of Facebook users. And while, yes, North Korea is again "dark", in this one China, right there to the northwest of India is noticeably "dark" (not the empty Tibetan Plateau, but the area to the east of that which, while not entirely dark, is certainly dimmer than its 1+ billion population would suggest):

Facebook has very little market penetration into China.... But that doesn't mean that China has no online social networking technology.  In fact theirs, known as QQ (or, more specifically, QZone) is even larger than Facebook.
