Agreed. I definitely think this is the sort of thing that would encourage you to share photos with your close friends (would you ping a random stranger for updates?). Think many smaller circles, instead of gigantic newsfeeds.

However, by nature of that alone, photos thusly shared are more likely to be of a private sort. I'm curious about what level of privacy these guys will offer and how they intend to back it up.
