Searching and filtering the vast amount of information on the web is one of the greatest obstacles to its utility. Initially, ranking pages based solely on their content, using algorithms like Google’s pagerank were enough. Then with the introduction of rolling content like weblogs, the need to prioritize current information over stale information became important and sites like technorati emerged. Now, the web is going local and search tools like yahoo local allow people to find static content around them – nearby services and content. Finally, with location based services linking the web to mobile devices, this local content becomes dynamic and ever-changing, based on the people who are nearby.
