Abstract: In general, the subject matter described in this specification can be embodied in methods, systems and program products. A server system receives from a plurality of computing devices indications that a user of each of the computing devices requested to receive posts that a first user authors. The server system receives from a first computing device a post that was authored by the first user. The post is transmitted from the server system to the plurality of computing devices. A score for the post is determined to satisfy a criteria for transmission to a second user who has not requested to receive posts authored by the first user. The determination uses a distance of the second user to the first user in a social network graph. In response, the post is transmitted from the server system to a second computing device that is associated with the second user.

Abstract: A first single-action input is received indicating a start tracking request and including information identifying a first current location of a user-controlled object on a user display device. A second single-action input is received indicating a movement of the object across the display device to a first different location and including a stop tracking request. A first display object associated with the first current location and a second display object associated with the first different location are determined. A group of selected display objects is determined including the first and second display objects. Display objects associated with locations displayed in an area spanning a first region located between the first current location and the first different location are determined, where a selection of the selected display objects is based on the first start tracking request and the first stop tracking request, with no input associated with a modifier input.
