Wait, what’s Qzone you ask?
“The site, part of the larger Tencent internet portal, claims to have had more than 200 million monthly active users in January, according to China Web2.0 Review (a translated version of the release is also available at the Web2Asia blog). Facebook, otherwise considered the largest social network in the world, self-reported 175 million monthly active users earlier in February.”
If this self-reported number is to be believed, then in fact, Qzone is the largest social network in the world. We were surprised too.
VentureBeat points out that web traffic analysis is quite poor, and that Chinese investors generally don’t trust third party analytics based in China. Head to VentureBeat and dive into the investigation there.
