Facebook announced today that it is launching a new social plugin called Shared Activity. With the plugin, developers can give people a way to control the activity they share to Facebook from their web apps.

“The plugin provides a simple solution for implementing the user controls required when working with Open Graph built-in actions,” explains Facebook’s Andrew Chen. “From the plugin on sites such as Airbnb, people can set the default Facebook audience for activity shared from your app, or manage the settings for stories previously published to Facebook, including selecting an audience or removing it altogether.”

The plugin lists people’s activities published from the app to Facebook, such as Open Graph activities, Like button stories, and comment plugin activity.

“For example, when an individual uses a music app, she could modify the privacy settings, through the plugin, for specific song listening activities, without needing to go back to Facebook to control what’s shown,” says Chen. “Similarly, if a person, through a travel app, likes a restaurant or reviews a hotel, and decides that these activities should only be viewable to a select group on friends on Facebook, he can control this within the plugin as well.”
