Condoleezza Rice and Bono grab the headlines for their diplomatic efforts, but there are others fanned out across the globe, everyday ambassadors quietly dispelling myths about their own and other nationalities. Their movement, at least 45,000 strong, began with a few people posing a new idea for the barter system: home exchanges.
Karl Costabel, owner of HomeLink USA, which dates to 1953, says: "We are, and I suspect will remain, a niche market. Our main demographic is the psychological profile of the individual: They must be easygoing and open to the idea of turning over their home to a stranger. There is little middle ground. When a person hears about this, there are two common reactions, either 'This is great, how do I join,' or 'You'd have to be totally deranged to offer your home to a stranger.' I tell people openly that if they have any concerns about security they should not join as they would not be able to enjoy their vacation."
