I am still in doubt. According to some international surveys, in the list of the world’s largest social networks, ranked in terms of reported or estimated global Monthly Active Users or MAUs, WeChat (236 million MAUs) stands at position 10. Some write in China Daily: 500 million users with 100 million outside of China. Or some say 400 million. Anybody has a better opinion?
The “international view” (BI Intelligence), gives this ranking:
1.Facebook (1.15 billion MAUs)
2.  YouTube (1 billion MAUs)
3. Qzone (712 million total users), China
4. Sina Weibo (500 million total users), China
5. WhatsApp (350 million MAUs)
6. Google+ (327 million MAUs)
7. Tumblr (300 million monthly unique visitors)
8. LINE (275 million total active users), Japan
9. Twitter (240 million MAUs)
