The thing that has always irked me is that under the Settings for the app on your phone you have General Settings, Notification Settings and Other Settings, but there is nothing under Other Settings. What gives? Is this like Bed Bath and Beyond where no one knows what the crap the Beyond is for?
It is just sad that a company as big as Facebook that has been around from some time now cannot get something as simple as Push Notifications to work properly, but you have Google+ that hasn't even been publicly out for half a year now and they had them working on their Beta versions of their app for those who had Invites. Also you got rinky-dink third party companies who create Facebook apps that obviously know how to get it work. Hey Zuck why don't you hire on some of these Developers who know what they are doing to finally get your program to work?
