Sharma and all of his colleagues then switched to WhatsApp. The app is not only simpler to use and is much faster but also allowed Sharma to create a specific group that he can use for group discussion with his colleague. Wait, what? WhatsApp's "last seen" feature is hardly an indication of who's online, and Hangouts allows for group chats... Are we sure that the backend behind Hangouts is much different from Talk? I suspect not, but there must be something causing all of the complaints of slow/poor delivery. Bad HCI/UX?
