When Google+ arrived at the end of June, it made a splash in part based on its defining notion: you have different kinds of friends and don’t want to share everything with all of them all of the time. This week a new iPhone group-messaging app called Katangoo is debuting. And its defining feature–which it came up with a long time before Google+ went public–is that people have different kinds of friends and dont want to share everything with all of them all of the time.
Katango’s distinctive feature is that it uses artificial intelligence to analyze all your Facebook friends, identify common attributes, and then automatically sort them into groups of people with something in common. The more friends you have, the more time this approach might save compared to you trying to organize them by hand.
