A new site called Circle Hack uses a drag-and-drop format similar to that lets you organize your Facebook friends into lists quickly and easily. Four Facebook engineers built the site, though it is not an official Facebook product, according to .

The new site does a pretty fair imitation of the . Like Circles, the page is divided into two parts. Up top are all your Facebook friends represented by their name and profile picture on a contact card. Below your friends is the area where you create new circles. Each section has its own scroll bar and you can even resize each section by clicking on the dividing line between the two areas.

Here's how you get started.

Log in to your Facebook account and authorize the site just like you would any other Facebook application. Then just start dragging your friends into the circles below. You can organize people individually or you can select multiple people at once. Circle Hack even includes a similar paperclip graphic to Google+ that shows how many people you're dragging into the current circle.

Once you have a circle organized click on the "Create list" link that appears in the center of your new circle to name it. After that, you're done and the next time you open Facebook, you'll see the newly created list as an option in the "Friends" section and in your privacy settings.
