Google+

One of the nice features is that you have circles of people, so you can set up family, friends, business, etc. When you make a comment, you decide which circle it is intended for and it is only viewable by that group. You can set up a category of people that you follow, and comments can be sent to them independently or you can send to all groups. Below each comment box are icons to add pictures, links, video, location, and this makes it extremely easy to attach. Another feature is that you can add people to your circles so that they receive emails only and do not have to join Google+.
