Four engineers of Facebook have joined to form a new product of Facebook called as Circle Hack, although TechCrunch declares that its launch has not been officially made by Facebook.
Circle Hack is a new website which is similar to Circles on Google+ and operates on drag-and-drop format; it will allow you to list your Facebook friends into lists quickly and easily.
The new site is divided into two parts just similar to Google+ Circles. The upper position comprises of Facebook friends that are represented by their name and profile picture on a contact card. The lower portion consists of area where you create new circles. By clicking on the dividing line of two portions you can resize each section and moreover each section has its own scroll bar.
To start with the site you have to login to your Facebook account and operate this site just like any other application of Facebbok. After this you can start dragging of your friends into the circle below. This will give you individual selecting option along with multiple selection option at one time. The site has one more similarity like Google + Circles, it has paperclip graphic that illustrate how many people you're dragging into the current circle.
A link appears in the center of the circle named as "Create list" after organizing the circle to name the circle. This is the last step and next time whenever you will open Facebook, you'll see the newly created list as an option in the "Friends" section and in your privacy settings.
