This document summarizes a geo-social mobile application called CO-LOCO that aims to explore location-based social networking. The application allows users to tag locations, interact with other users nearby via messaging or comments on points of interest. It uses a client-server architecture with an XML interface and a lightweight mobile mapping and location component. Key issues discussed include usability of maps on small screens, data overhead of map tiles, and user privacy and acceptance concerns around sharing location information. The document concludes that improved interfaces, larger user testing, and caching strategies could help address technical barriers and prioritize usability and privacy for such applications.
