While the media continues to call SINA (NASDAQ:SINA) Weibo China's main Twitter-like service, saying it doesn't make it so. Digging deeper into the numbers and looking at the broader social networking market, it seems like SINA stock will continue its two-year-and-counting decline.

In the video below, Fool contributor Kevin Chen details five reasons why SINA may be forever doomed: 

  1. SINA Weibo's daily active users may be exaggerated.
  2. Its registered users lag that of competitor Tencent (NASDAQOTH:TCEHY) Weibo.
  3. Its penetration rate trails Tencent Weibo.
  4. Its geographic make-up isn't poised for China's economic growth. Meanwhile, Tencent Weibo is.
  5. Renren (NYSE:RENN), the "Facebook of China," and gaming portal NetEase (NASDAQ:NTES) threaten SINA Weibo's viability as a social network.
