WhatsApp is one step closer to a billion regular users. The Facebook-owned chatting application released its latest metrics, and it has a whopping 700 monthly active users. That makes it far and away the world’s most popular chatting application, compared to the most recent figures — WeChat’s 438 million and Facebook Messenger’s 500 million. It also comes out ahead of most social applications, given Instagram just hit 300 million, Twitter is at 284 million, and Snapchat was reportedly at 100 million in August. The numbers come at a rather strange time, less than a day after Twitter and Medium co-founder Ev Williams wrote a scathing indictment of using such metrics to track a product’s impact.
