Abstract: Personal experiences of users are cataloged into a Library, all aspects of which are specifically tied to a location. Users are linked to other users and to groups of common interest. Personal experiences are searched by users based on content category and locations. Search results are filtered based on content, links between searchers and content creators; and rated for relevance. Commercial content is targeted to users to help identify goods and services of interest based on search results. The resulting social networking system provides credible information and opinions about places in which the user has an interest and reliable data about that interest and targeted advertising opportunities to commercial sponsors.
