Facebook today launched the Shared Activity plugin for developers, which allows Facebook users a way to control the activity they share to Facebook directly from external web apps.

Facebook’ Software Engineer Andrew Chen offered an example (image at right) on  Developer Blog  on how this new plugin works:

“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.”

Shared Activity  plugin gives Facebook users ease of control of who gets to see their activity. For instance, if a user doesn’t want the general public to see what stories she likes in a certain app, or her comments within it, they can adjust that without leaving the application and going to Facebook.
