Facebook today announced that it's opening up Facebook Messenger to folks who don't actually use Facebook. Going forward, all you'll need to use the Messenger app is a name and phone number, and you'll be able to hit up your mobile contacts. The obvious play is to get non-Facebook users to stick a toe into the water -- and not into the pools of cross-platform competitors such as Whatsapp. Whether the Facebook name remains too much of a deterrent, we'll just have to see.
Facebook says an update to the Android client should be rolling out today (it's not live as of this writing).
