We were all former loyal users of Flickr or Picassa, and every time we came back from a trip, we diligently uploaded all the photos to the Internet and sent the links to our family and friends. But not only did they have little interest in looking at these pictures, even we ourselves couldn't remember the stories behind the photos anymore, and those photos just sat there never to be looked at again. So, what's wrong with the current photo-sharing model?
