Adam Ostrow at Mashable.com highlights a few interesting findings from the report:

“The massive impact of China: The vast Internet population coupled with hugely socially active set of web users, makes for a massive volume of content creators. However due to the inward looking nature of Chinas internet economy combined with the language mean that this volume of content does not impact the broader Internet

Low engagement in Japan: We also associate Japan with technology innovation, and actual while you might not think it, the low engagement is indicative of progress. Why? Our map shows PC activity and we know from this research that a huge number of Japanese users are bypassing PC altogether and using mobile devices to access social platforms and create and share content. Just over 34% of social network users only accessed through mobile in the month of the research, this is compared to 3% in the UK, a staggering indication of where the future is heading.

The low level of microblog engagement: Despite the Twitter hype, microblogging is still not a mass social activity and nowhere near the size and scale of blogging.”
