Here's where the comparison with WeChat maybe breaks down. I lived in China for years, right during the time that WeChat (WeiXin) came out and evolved to become the "everything" app (vanquishing Weibo and others). But I've only used WhatsApp for text messages and didn't even know that it had all these other features until I read this article. So maybe it isn't really comparable to WeChat in that sense -- or maybe it is, I don't really know actually.
