Tencent's Xiaoyou

I came across QQ for the first time in 2001. I was a new transplant to Beijing at the time, and even then, QQ rivaled (likely surpassed) ICQ in popularity. Registering for QQ via mobile phone was pretty commonplace in 2001. Curious to see the latest 411 on Tencent (granted, the link I've provided is already considered old news)...
