It's probably the hottest shit right now in China in terms of social networking, and is probably only second to QQ (which I will not cover here, as I have no experience with it).
Gaming in China and not having either QQ or We Chat is the equivalent of gaming back home without Facebook/Whatsapp/i Message and whatnot, and believe me in China it's even more important.
I can count on my hands the number of things I can say in Mandarin (one of which now being the Chinese word for Orgasm, fuck yeah), so I was gaming strictly in English.
Probably a lot of what I'm going to write now will be irrelevant if you are Asian looking and/or have a good grasp of Mandarin and/or not a tourist.

What is exciting, is that We Chat has a set of tools built in it that are meant to enable you to meet new people, the most important of them being one based on Geolocation.
Using the right techniques, this little piece of software, and that specific feature can completely change your game while in China, so stay tuned.
If you meet a girl in China between the ages of 18-30 and she has a smartphone, she has We Chat and/or QQ.
But, this is just a tool for communicating, which in itself isn't all that exciting.
So I've been lurking around here for a while, but somehow this topic was never really fully covered, so I came here to fix that and share my experience.
First of all to all those who don't know what We Chat is: Think Chinese "Whatsapp" meeting Facebook with Geolocation functions.
