The DivShare Facebook application lets you easily share files with your friends network on Facebook.
You'll need to first be registered with DivShare, which can be done within Facebook. Once you upload a file, you can type in the name of one of your Facebook friends, in a very similar manner to "sharing" an item on Facebook. After choosing a friend to share a file with, you can opt to post the file in your profile and/or your newsfeed. You're immediately directed to the "send file" page once your file has been sent. This application is very easy to use, and enables a level of privacy that is somewhat more complicated to achieve with Facebook alone.
