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 indicates where 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 33% 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.
