I got an invite when it was in beta and i was very excited. So i logged in and realized i didn't have anyone to use it with and so i can vouch for how well it works. Although i would like to use it if i knew people who used it. Its lack of wide spread average Joe adoption is limiting it in my opinion but it may prove very useful in a work setting.
