A News.com story discusses the increasing trend towards adding metadata to casually created content. Their discussion centers around vacation photos taken with increasingly sophisticated cameras, and uploaded to ever more feature-rich websites. These photos, taken on a whim by snap-happy tourists, become invaluable for people wanting to follow in their footsteps. "It's the odd juxtapositions of randomly plotted photos that may be the most surprising--and useful--to travelers with more obscure interests. For example, fans of graffiti can search the word, 'graffiti,' and 'New York City' at Flickr.com/map, and pull up photos of freshly painted tags, all plotted with pushpins on a clickable Yahoo map. A search for 'Dumbo Brooklyn graffiti,' for example, finds some 99 photos, including the infamous 'Neck Face' tag, spray-painted on a brick warehouse at Jay and Front Streets in Brooklyn. Try finding that in a guidebook."
