This paper presents the GeoFeed system; a location-aware news feed system that provides a new platform for its users to get spatially related message updates from either their friends or favorite news sources. GeoFeed distinguishes itself from all existing news feed systems in that it enables users to post message with spatial extent rather than static point locations, and takes into account their locations when computing news feed for them. GeoFeed is equipped with three different approaches for delivering the news feed to its users, namely, spatial pull, spatial push, and shared push.
