Social Media is running hot in China right now. A recent study by McKinsey revealed that 91% of all Internet users in China, have used Social Media in the past 6 months – that's 467 million Chinese consumers. So just who are these consumers and what are they using? Weibo takes top spot in most categories. Curiously, as a sign of China's growing wealth, users of the top-4 social media sites all have a household income of more than $15,000 USD per annum.
