It has been seen many times when you use some apps and all of your friends come to know about this through post on your wall and it is very irritating. So keeping this in mind Facebook has launched new privacy settings for applications which will enable you to personalize the audience while using apps.You can find more about this in Facebook Blog.

This will give you power to set your post to be visible to your choice of people. I just checked it with an application and got this update right away where I could change the privacy settings myself. You may also see applications asking users to set privacy settings.
