Have a bad case of Google+ envy? Here's a little something that should help hold you over until the site fully opens its flood gates. Circle Hack is a self-described "one-night experiment with Javascript" created by a few Facebook engineers in a non-affiliated capacity, which unofficially brings Google Circles-like functionality to the top social network. The creators of the Facebook plug-in have borrowed liberally from Google on this one (turnabout is fair play, perhaps). Once you log in with your Facebook account, you can drag and drop rectangles of your friends from that site into circles at the bottom of your page -- a quick method for curating your Facebook lists. Given the short development of the plug-in, the functionality of the site is, not surprisingly, a bit limited. Certain things like, say, deleting circles, are absent at present -- perhaps its creators are too busy working on the Facebook Hangouts hack.
