Facebook may want WhatsApp to remain a regular messaging app, but Facebook Messenger is a whole other story. With Messenger, Facebook wants to emulate the messaging giants of Asia that haven’t found much success in the West, which means the company wants to turn Messenger into the digital equivalent of a Swiss Army knife. The idea behind this type of messaging app is that you never really have to leave it in order to do things, because every app or feature you’re ever going to need is already integrated into the app. The Information reported on Monday that Facebook even wants users to be able to pay for things within the Messenger app.
