In Sunlit you create stories that combine photos, location check-ins, and text. For trips, events, or any memories. You can share them with friends and everything syncs automatically.
Really great app and it's built off of the App.net backbone. I've been playing with it for a bit and I think this is going to be a great way to share moments in your life with family and friends. Previously I was using a shared Photo Stream, but this has a web component which makes things much easier.
