It is interesting how they provided the identical functionality as new Facebook Groups - they ripped-off Facebook's interface, then Facebook ripped-off their feature. It seems they were also inspired by Paul Adams' circles. I simply don't like that approach as anybody from the group can invite new people and anybody can add me to a group without my approval. Google circles will win.
