According to Facebook, the messenger app is for those who gonna have a new account further. And the good thing is it wouldn't affect those who already had created a messenger account by their phone number.
Facebook has also developed a system called "crush platform messaging". Facebook has already informed that there gonna be a "cross-platform messaging" option on Instagram, Messenger and WhatsApp i.e a person can directly message from WhatsApp to Instagram.
Facebook's own operating system
Facebook is launching its own "operating system" so that it can ditch apple´s IOS and google's android.
Facebook has given a responsibility to Mark Lucovsky who makes a "windows anti-operating system" for Microsoft. It is done to prove that the facebook hardware´s vice head Andrew Bosworth´s company´s previous aim was space.
He also said "We don't want to depend upon others. We want to discover and invent everything we need". He added that the plant had already been developed.
