A photographer, John Heller, had $9,000 worth of gear stolen at a shoot in Hollywood. After giving up all hope of ever getting his Nikon D3 back, he checked with a site called GadgetTrak that scans Flickr and other image upload sites for photos matching the serial number of his DSLR. In a few seconds he had found shots with serial numbers matching his D3 belonging to a professional photographer. With the help of the police he got his gear back and now the tracking service is a recommend site for LAPD detectives on the hunt for fugitive cameras.
