Earlier quoted context omitted.
Isn't there inherent risk in centralizing / relying on one app for so many activities? There are already many in the West that try to avoid relying on everything Facebook or Google due to privacy/security concerns. I'm surprised that Chinese are willing to put all their eggs in WeChat's basket, given their belief that American apps spy on their users.
That's exactly what makes the problem so interesting. The user experience of WeChat is clearly great, but that level of centralization really wouldn't fly over here.
Many people, including me, use *.google.com as a one-stop shop for all their software needs.
