Russia #1 Worldwide in Time Spent on Social Networking Sites
In August 2010, 34.5 million Russian internet users (74.5 percent of the online population) visited at least one social networking site.

However, its audience has grown 376 percent in the past year, outpacing each of the other top five social networking sites in the market.
