Social media sites are often seen as places to swap gossip, share photos and waste time, but they are increasingly being used in the hunt for missing persons.One such case is the hunt for six-year-old Andrew Thompson, who was reunited with his father in the Netherlands last week after a two-and-a-half year search.Mr Thompson’s desire to track down his son was so great that he quit his job as a deputy fire chief, mounted a bicycle and rode 6,500 kilometres through Europe to find him.
