Along with the “Facebook Subscribe,” the social networking company will soon let you update Twitter right from the Facebook.
Once you link your accounts, your Twitter account will be updated every time you post a public update to Facebook. Note: Only posts whose privacy you set to Public using your inline controls are eligible for this.
As point 14 in the document embedded below states:
