Despite the idea of "being in Cyberspace" and the power of the Internet to connect us to people all over the world regardless of our location, we often use a browser to find out about people and services close to us. These might be queries such as finding the opening times of a local store, the time of a train or local expertise. Each time we do this it is often necessary to tell the website where we are, typcially by providing a post code, but what if you don't know the postcode? Fortunately browsers and becoming much more clever, and some can even work out where you are.
