Abstract: A system for managing a geographic index of affinity (GIA), defined as a distance a user is willing to find/connect with other users, specific to a particular shared interest. The GIA includes a degree of distance (Affinity) based on their geographic location and can be used in conjunction with free online Web services to deliver a steady and relevant pool of meaningful connections based on interest-specific GIAs. This provides an advantage of capitalizing on blind spots and shortfalls in current social networking platforms by building sites where users build communities of trust, and, in the process, make themselves open to relevant local advertising. As desired, user demographic databases are built that include specific interests, approximate location, age and gender of the users using the GIA.
