Katango Adds Google+ Circles Behavior To Facebook On iPhone

One of the distinguishing features of Google+ is its simplicity for grouping people who you follow by simply dragging and dropping their names into circles. Facebook’s Groups has the same functionality without the fancy UI, but the problem is that Groups didn’t appear until after most of us accumulated dozens, if not hundreds, of friends, and it is too much work to put hundreds of friend into groups. Katango is an iPhone app that scans through your Facebook friends and automatically puts them into groups.
