Has anybody joined the beta for the social service? I think it will eventually beat out facebook. There is an option to only post to select groups meaning: you can put people in select groups and only post to them. So you can have family in one group and friends in another an only post to friends or to family, or if one person is on both they will get the post. Pretty sick. The interface is pretty well laid out. Only trouble I had was actually getting to the point of viewing other people profiles was a little tough. Overall clean and easy.
