The feature was created during a Facebook hackathon by developer Ryan Patterson and another FB engineer. It has enough traction with Facebook that it was being ‘used’ at the Angelhack event in Seattle. TechCrunch first reported the new app and its unofficial introduction to the world.
We first heard about the service from developer Roger Pincombe, who himself got the info from a Facebook developer at the Angelhack event going on this weekend: Facebook is a title sponsor, and at the San Francisco event (Angelhack’s taking place also in Seattle, Boston and NYC), and one of its engineers was on site showing off how the app worked with developers. The feature has not been officially launched, but it is live and visible for those seeking it out.
