I like to see US rockstar startup coming to China. They will encounter fierce competition as clones started blooming here more than 1 year ago so they had time to iterate and adapt their services perfectly to the Chinese market.

Going to the Chinamode Awards at the end of this month (Awards voted by Chinese netizens to their favourite online services), 3 out of the 5 winners of the category Best Consumer-based services are Group-buying services with Chinese characteristics…They could be good candidate for an offer! Rumors from Mobinode blog says Jiepang (Chinese most popular LBS) is also a candidate…
