Check this link guys http://t.co/flxYts4 Facebook engineers Vladimir Kolesnikov, Peng Fan, Zahan Malkani, and Brian Rosenthal wanted to be able to organize their Facebook friends in the same way you can organize them using Google+. Since it took a bit of hacking, the team of four has called it Circle Hack and described it as “A one-night experiment with JavaScript (not affiliated with Facebook).†You can organize your friends on Facebook as well with a feature called Lists. But setting up a list is much more complicated on Facebook, than setting up a Circle is on Google+. Although Circle Hack is not an official Facebook product, it does show that Facebook employees care about fixing certain aspects of the social network. The new website is a pretty good imitation of the Google+ Circles feature. I hope that Google+ and Circle Hack inspire Facebook to fix how Lists are created on the social network.
yes, its integrated and we need not go out of google+, but circle hacks is just a one night experiment, and i did not see any difference in between these two... so how is it better
Still most of them including me are on FB train, though some of us also have a ticket for Google Train, we can jump over only when Google catches up with FB train, that's the correct moment for us to jump. Else we will be waiting on the tracks for Google Train to come and pick us up or left behind atleast until the day it will overtake FB train.
