The US Library of Congress knows how to share. It is steadily adding hundreds of extraordinary photos to its bit (link)the picture sharing website flickr. They are using the site because i allows the public to add to the significance of the pictures. We can use keywords to describe them, add extra details or information about the people or places in the comments and even use google maps and other website to mark where the photo was taken. It is such a simple idea. So, does Birmingham have a photostash which ought to be seen and catalogued by crowd? Hat tip Peter Bradwell at Demos.
