While Facebook users were busy posting and tweeting about its new look and new features, mobile content developers were absorbing the latest news about Facebook Mobile – the service now has 350 million active monthly users, up 100 million in the last six months. According to Inside Mobile Apps, Facebook for iPhone now has 90.1 million active monthly users, Facebook for Android has 65 million, and Facebook for BlackBerry has 44 million. Facebook for Android is growing the fastest, adding about 6 million new active users each month. Facebook for “Every Phone” is holding steady at about 31 million active monthly users, and Facebook for the Windows phone has fewer than a million active monthly users.
Meanwhile at Facebook’s F8 developer conference Thursday, founder and CEO Mark Zuckerberg introduced Open Graph, calling it a “whole new class of apps.” He said it will create a “frictionless” user experience because apps will not have to ask permission every time content is posted to Facebook. Instead, there will be a new Facebook permissions screen that users will complete one time. Facebook is encouraging developers to increase distribution of their apps by making use of Facebook’s timeline, news feed and ticker. The company is making the Open Graph Beta avaiable to all Facebook developers. Facebook CTO Bret Taylor said yesterday that Facebook has no plans to open its own app store.
