Have you worn a "围脖" today? Lately, this sentence has become popular among the youth. Perhaps those who are not familiar with the trend might be totally lost, but fashion-seeking "net worms" all know that the so-called "围脖" is actually the burgeoning microblog on the Internet, or briefly called "微博". These days, without a 围脖, you wouldn't even feel comfortable to say hello to others... From the foreign microblog pioneer Twitter to the domestic giants Sina Weibo and Tencent Weibo. Under such a big trend, microblog has already become a must-contest area for online marketers.
