Facebook will on Wednesday launch the Open Graph applications it first debuted last September, sources told AllThingsD. These are the apps, made by outside developers, that “frictionlessly” and continuously share users’ actions back to Facebook after a user has given permission once.
The new apps behave similarly to the “read,” “listen” and “watch” Open Graph applications that have already rolled out in the past few months, which include the Washington Post, Spotify and Hulu. So every time your friends read an article or listen to a song, you might now learn about it on Facebook, and possibly even join them in reading or listening at the same time.
Facebook: “frictionlessly” tracking your every move.
