I've been keeping my eye on this site http://www.blockchain.info/nodes-globe?series=48hrs where they show the active nodes in the past 48hrs for a few months now.
What I've been seeing is that there are many new nodes appearing in Asia in the past two months where it was nearly completely dark.
Will 2012 be the year that the giants like China and India among other countries start embracing bitcoin? One thing for sure is that the news of bitcoin is definitely spreading into these area.
The bars at Beijing, Seoul, and Taipei have been growing fast and small bars have been appearing all over the Southeast Asia as well as India.
It will be really exciting to see new exchanges and services appear in these area in 2012.
