Abstract: In general, the subject matter described in this specification can be embodied in methods, systems, and program products. A request that a server system deliver textual posts to a computing device may be received. Posts may be associated with a geographical place of posting and a temporal age. A value that represents a geographical distance from the computing device to the geographical place of posting can be identified. A score for a post may be based on the value that represents the geographical distance and the temporal age of the post. An indication of the score for the particular post may be provided to the computing device so as to cause the computing device to display an indication of the post and to visibly indicate a prominence of the post. The indication of prominence of the post is based on the indication of the score for the post.

Abstract: Some techniques feature a computer-implemented method for messages associated with a user location. The method involves determining, by a mobile computing device, an estimated geographic location of the mobile computing device. The method includes receiving, at the mobile computing device, one or more messages associated with an area within the estimated geographic location, where the one or more messages include messages posted by users of a system that associates messages that those users posted about the area within the estimated geographic location. The method involves providing, on a display of the mobile computing device, one or more posted message icons that are presented in a layer over a map, where the one or more posted message icons represent the one or more posted messages. In a system, the one or more posted messages may not appear on mobile devices after a predetermined amount of time from their respective postings.
