WeChat has 438m monthly active users

"Chinese web giant Tencent (HKG:0700) has just released its Q2 earnings report. We’ll look at the financials later, but first the number that we all want to see – Tencent’s messaging app, WeChat, is now at 438.2 million monthly active users (MAUs).
Social gaming tied to WeChat and QQ (Tencent’s old MSN-style instant messaging service) generated RMB 3 billion (US$487.4 million) in revenue in Q2.
That newest WeChat MAU figure is up from 396 million in Q1; it’s risen from 236 million at the same period last year.
[...]
For a sense of scale, Facebook-owned WhatsApp has 500 million MAUs. However, Tencent is still not revealing how many active users it has outside of China."
