I do feel like a cause for camera-hoarding is that you never know when someone will want a new copy of a photo or if you'll yourself need a new copy (in case of theft, etc), so you want to keep the camera around in case you'd like to print more copies of the photo.
This begs the question - how can we make photo-sharing and photo-storing easier? I feel that preserving Withmore's history is incredibly important. It's always incredible to come across literal decades-old photos in SD, as well as enjoy looking back at photos from one's immy years. The same goes for newspapers, flyers, and letters, of course, but photos are unique in that they're taken generally for the express purpose of keeping memories around.
