Forget Facebook or Twitter. With the inadvertent help of Chinese government censorship, an app called WeChat has taken over the lives of Chinese-Americans. It's part family lifeline, part public square, part dating site and it could be a model for the evolution of social networks. 

This week on New Tech City, hear what's so special about WeChat as we journey through the hilarious story of a vexed husband trying to understand what makes this app so addictive and pervasive in Chinese-American circles. There's annoying patriotic sausages, smokey hot ladies, and a global tech ethnographer all mixed together. Good times.
