Facebook spent 16 billion dollars on some kind of mobile phone app? We heard something about that, but we're not really sure what you guys are doing outside China. Because we have our own thing going on in the mobile chat space, and pretty much everyone in this country of 1.3 billion mobile users is on it. So you should get on it too.

Learning Chinese? In today's show, we feature two dialogues about asking someone for their Wechat/Weixin number. This is a useful way of hooking up with new friends, and a non-threatening way to meet new people -- it's not as aggressive as asking someone for their phone number, and it lets you find out more about them through an entirely new and innovative method of digital stalking. Needless to say, we highly recommend it.
