Creating real-time conversations

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for creating conversations related to a location. One method includes receiving a topic for a real-time conversation from a user, receiving location information related to a location of the user, and creating a real-time conversation object that includes the received topic. The method also includes tagging the created real-time conversation object with the received location information, indexing, based on the received topic and the received location information, the tagged real-time conversation object with respect to other real-time conversation objects, and providing the tagged real-time conversation object in response to a search for real-time conversation objects received from another user.
