Online Review: Both are global social media giants, but Tencent can't compete with Twitter. Most world leaders, politicians, intellectuals, celebrities, and entrepreneurs are active on Twitter, directly engaging with the world. But over at Tencent, it's simply not happening. A department head, an ordinary civil servant, all with career positions, don't post on their moments; it's a dead silence, quietly slipping by, lacking vitality. Baidu and Tencent are accelerating towards withering, losing authenticity, losing vitality, losing the support of the people. Especially, Baidu's demise has already entered the countdown.
