This paper presents a multimodal social networking system aimed at sharing geographic information among proximate users. The system provides users with a traditional web-based interface along with a voice-based interface that can be accessed over a mobile phone. We describe the main design features of the system, different aspects of its functionality, as well as a number of design challenges imposed by multimodality on a social networking system. This paper also presents the results of the end-user acceptance study conducted to assess the usability of the system.
