This post is all about WeChat, but it’s also about more than just WeChat. While seemingly just a messaging app, WeChat is actually more of a portal, a platform, and even a mobile operating system depending on how you look at it.

Much has been written about WeChat in the context of messaging app trends, but few outside of China really understand how it works — and how it can pull off what for many companies (and countries) is still a far-off vision of a world managed entirely through our smartphones. Many of WeChat’s most interesting features — such as access to city services — are not even visible to users outside China. So why should people outside of China even care about WeChat? The first and most obvious reason is that it points to where Facebook and other messaging apps could head. Second, WeChat indicateswhere the future of mobile commerce may lie. Third, WeChat shows what it’s like to be both a platform and a mobile portal (what Yahoo could have been).

Ultimately, however, WeChat should matter to all of us because it shows what’s possible when an entire country — which currently has a smartphone penetration of 62% (that’s almost 1/3 of its population) — “leapfrogs” over the PC era directly to mobile. WeChat was not a product that started as a website and then was adapted for mobile, it was (to paraphrase a certain movie) born into it, molded by it.
