Worldwide use of Social Networking

Interesting visualization of Social Network penetration world wide by Global Web Index. The Netherlands scores average when it comes to content sharing & messaging but considerable less when it comes to joining/creating groups. Not something I would have expected!
Most notable though I find are the figures for Japan. For a country so obsessed by mobile gadgets you would expect them to be more active on Social Networks as well.
