Google cooperator Tianya opens an Answer service at wenda.tianya.cn. But according to the server IP, it is running on Google China’s servers. Tianya is one of the biggest online communities in China. Most users of Tianya are clerisy and patriot, accord with Google China user features.

Why on Google server? May be the reason is providing online community service need a government license. But the license only opens to Chinese corporation. So google has to publish it as one cooperator’s service.

Almost every search provider in China has its answer service. The leading one is Baidu Zhidao. Alexa.com shows Zhidao is the 6th service in Baidu, offers 5% traffic for Baidu.com, and now there are 20 million answered questions on Baidu Zhidao.

Four months ago, another Google associate, Tencent published its answer service Wenwen to compete the market.

Yodao opens a blog widget called BLOG MAGIC SQUARE. It contains article publish time statistics and gender analytics like Demographics Prediction in Adcenter. It based on Flash and users can choose different color theme to display.

The leading Chinese goods B2B Alibaba launches a website ads trade market called Alimama. Alimama is similar to combine Adwords and Adsense, but more like a C2C site.

Publishers can offer their websites’ place to show advertisements. Advertiser may pick appointed place or website to show their ads. A bit different and particular than Adwords.

Alibaba has hundreds of customers, so maybe Baidu and Google will in the face of a powerful competitor.
