Facebook recently rolled out a new way to view photos, but what’s been going on behind-the-scenes? We check out the latest news from Facebook’s blog post and put together a timeline of the changes they plan on implementing.
January 15, 2011 – In a post by Jeff Bowen, Platform Developer Relations at Facebook, they announced that they’re making a user addresses and mobile phone numbers accessible to third-party applications. They realize that this is sensitive information and have updated the user permissions to applications which must be granted by the user through a permissions dialog.
January 18, 2011 – In a post by Douglas Purdy, Facebook admits to receiving feedback about giving third-party applications access to contact information. They reiterate that only the user’s address and mobile phone will be accessible, and not their friends’ and that the user will have to make a choice to share the data before any app or site can access it. Users can always see and control how their information is used in Facebook’s Application Dashboard. Because of the feedback they received, Facebook will be temporarily disabling the feature until they roll out clearer parameters that users will understand.
January 31, 2011 – Facebook has announced that they are planning to host 12 Startup Days in 2011 to provide early-stage companies with engineering and design support on the Facebook Platform. This consists of monthly events for entrepreneurs to work with them in building new apps and websites that incorporate the latest social technologies.
February 25, 2011 – Due to some developer feedback, Facebook has adjusted their find/accept requests for developers within an app. They used to be found at the bottom of the Requests page
but have now been moved in the Developer app and Notifications. 
March 1, 2011 – Facebook requires social game developers on the platform to process all payments through Facebook Credits effective July 1.
March 1, 2011 – Facebook updates their Comments Box plugin with new moderation tools and features that improve distribution and quality of comments. Comments are now ordered to show the most relevant comments from friends, friends of friends, most liked, etc. Comments marked as spam will be hidden from view. Admins can now choose to make the default for new comments either “visible to everyone” or “has limited visibility.” Admins can also moderate comments directly or on the Moderation Dashboard.
Obviously, Facebook is hard at work with being up-to-date with users’ needs and concerns and with some recent reports of big companies investing in the social network, expect many more innovations to come in the following months.
