Twitter might be the fastest growing social platform while the activeness of China's Sina Weibo seemed decreased.
According to GlobalWebIndex, number of active Twitter users grew the fastest, 40% from Q2 2012 to Q4 2012, followed by Facebook.
GlobalWebIndex said the way people are using Twitter is changing in two respects. Firstly, it is becoming a passive source of discovery for users and secondly, users are using more as a tool or service rather than a pure social service. Amazingly, only 51% of active users claim to have posted a tweet in the past month. This means that half the active user base is just reading, reacting or using Twitter as a source of discovery. The caricature of the average Twitter user banally talking about what they had for breakfast is dying.
On the other hand, all the China social media saw reductin in active users. Tencent Weibo is the worst, 60% decrease. Sina Weibo has decreased over 35%.
