I have a Facebook user for about 9 years and seen how it develops. I don't have any issues with regards to its usage and enjoyed a lot from it. But I am a bit puzzled about the Facebook Messanger because it shows to be a stand alone application. As far as my memory remebered way back then, Facebook messaging is programmed along with the Facebook Application itself. Why is there a need to install another application for Facebook, which is the Messanger? I don't think it is benificial to the users because it just occupies another byte of memory.
Any idea why Facebook and Facebook Messenger are separate applications?
