Facebook debuts its phone app, Hello

In Facebook's ongoing quest to take over all aspects of our digital lives, the social media giant is now going after the least used thing on our mobile devices: the phone. That's right, Facebook wants us to talk to one another. And we're to do it with its new Hello app. The calling app (for Android) connects with Facebook to allow users to screen calls (even if the caller isn't in your phone contacts). Users can also search for people and businesses (and even make reservations). Calls are free when made over a Wi-Fi network. Will it last? Facebook's Messenger app was poorly received, but is hanging on. Expect mobile users to give this one a ring and then cut the cord.
