To me this is an unsung feature of the iPhone 5 and iOS 6. Shared Photo Streams is sort of like a mini Facebook, enabling you to share the photos you want with the people you choose. From there, friends and family can like or comment on your photos, and it's easy to add to that stream later on. This came in handy when I wanted to pass on some pics that I shot at the toy store of what the kids want for Christmas. Samsung has something similar with its Share Shot feature, but it works only over a local Wi-Fi connection, not the Web.
