Abstract: An external system (e.g., a website) is associated with an event and includes an interface that allows users to interact with streams of content associated with a social networking system. The interface allows a user to provide posts about the event via the interface, where the posts are displayed in the interface and also in a social networking interface on social networking system in connection with the user and other users associated with that user. The user can view, via the interface on the external system, posts from all users that are provided via the interface (e.g., everyone watching the event), thereby increasing the likelihood that the posts are relevant to the event. The user can also view, via the interface, posts from users associated with the user via the social networking system (e.g., friends of the user), regardless of where those are posted.

Abstract: In one embodiment, a method includes receiving multiple recommendations for a first user from multiple second users and the multiple recommendations are associated with multiple objects. The multiple second users select the first user as the addresses of the multiple recommendations. The method also includes determining that the first user is near a geo-location and recommending to the first user multiple objects that are associated with the geo-location.

Abstract: A social networking system provides a short, unbiased biographical summary for a user of the social networking system. The short biography includes a few relevant biographical information items selected from the user's profile and is displayed on the profile page. The short biography may be displayed with a set of photographs also selected from the profile for their relevance. Relevance may be based on various information including temporal relevance and relevance to the viewing user. Display of the short biography allows a viewer to easily find current biographical information about the user in an abbreviated format.

Abstract: In one embodiment, a method includes determining a current geo-location of a mobile client computing device associated with a first user; and selecting content associated with the current geo-location that was provided by a second user. The selection is based at least in part on a relationship between the first and second users. The method also includes sending to the mobile client computing device while the mobile client computing device is at or near the current geo-location a notification associated with the content.

Abstract: In one embodiment, a computer system accesses for a first user contact information of one or more second users. The computer system then determines one or more contemporaneous attributes of the first user, determines one or more contemporaneous attributes of each of the second users, and then dynamically sorts the contact information of the second users based at least on the contemporaneous attributes of the first user and the contemporaneous attributes of the second users. The computer system then provides the sorted contact information of the second users for display to the first user.

Abstract: In one embodiment, a method includes determining a geo-location of a first user; and identifying a second user that the geo-location of the first user is of interest to. The second user is identified based at least in part on a relationship between the first and second users. The method also includes sending to a mobile client computing device associated with the second user a notification associated with the geo-location of the first user.

Abstract: In one embodiment, a method includes receiving a number of recommendations for a first user. Each recommendation being made by a second user and including information that: identifies an item being recommended; provides an explanation for the recommendation; identifies the first user as an addressee of the recommendation; and identifies the second user as an author of the recommendation. The method also includes providing for presentation to the first user one or more of the recommendations.

Abstract: A social networking system user identifies one or more social networking system users authorized to present content items to the user via the social networking system (“authorized users”). When an additional user requests presentation of a content item to the user, the social networking system determines if the additional user is an authorized user. If the additional user is an authorized user, the content item is presented to the user. However, if the additional user is not an authorized user, the social networking system identifies the additional user to the user along with a request to identify the additional user as an authorized user. If the user identifies the additional user as an authorized user in response to the request, the content item is presented to the user.

Abstract: A messaging system facilitates communication between users through various messaging channels. The messaging system supports multiple communication channels and includes a messaging module that automatically selects one or more of the messaging channels for delivering a message to a recipient of the message using, for example, a set of policy rules or a trained model. The messaging module may also provide, in a user interface for sending and receiving messages, a visual indication of the selected messaging channel to the sender of the message to provide the user with transparency about how the message will be delivered. Additionally, the message may be delivered via multiple messaging channels, where the messaging module may rescind messages from some of the messaging channels upon receiving a reply from the recipient of the message or other confirmation that the recipient has seen the message via one of the communication channels.

Abstract: Physical social actions are conveniently detected, characterized, and provided to a social networking system. This improves the user experience of the social networking system by more thoroughly recording the social actions of users occurring outside a social graph. This has the effect of extending an open social graph, which typically refers to social actions taken outside the social networking system but within a computer network, to physical social actions. By providing characterized physical social actions to the social networking system, the open social graph is extended to include physical social actions.

Abstract: A user interacts with a messaging application on a client device to capture and send images to contacts or connections of the user, with a single user interaction. The messaging application installed on the client device, presents to the user a user interface. The user interface includes a camera view, and a face tray. The messaging application automatically populates the face tray with contact icons associated with one or more contacts. The messaging application identifies contacts associated with the user and attributes associated with the contacts. Based on one or more attributes, the messaging application may rank the contacts. Based on the rank associated with the contacts, the messaging application selects one or more contacts to include in the face tray to present to the user or to provide to the user from which the user can select contacts to include in the face tray.

Abstract: A user interacts with a messaging application on a client device to capture and send images to contacts or connections of the user, with a single user interaction. The messaging application installed on the client device, presents to the user a user interface. The user interface includes a camera view and a face tray including contact icons. On receiving a single user interaction with a contact icon in the face tray, the messaging application captures an image including the current camera view presented to the user, and sends the captured image to the contact represented by the contact icon. In another example, the messaging application may receive a single user interaction with a contact icon for a threshold period of time, and may capture a video for the threshold period of time, and send the captured video to the contact.
