Abstract: Systems, methods, and non-transitory computer-readable media can determine that a broadcaster of a first live content stream has identified at least one user of a social networking system to join as co-broadcaster. A merged live content stream is published through the social networking system, the merged live content stream including the first live content stream of the broadcaster and a second live content stream associated with the at least one identified user. At least one notification is sent to one or more other users of the social networking system. The notification informs the one or more other users about the merged live content stream.

Abstract: Systems, methods, and non-transitory computer-readable media can determine that broadcasting of a live content stream has concluded. The concluded live content stream is converted to a post live media content item. The post live media content item corresponding to the concluded live content stream is published through the social networking system. The post live media content item remains accessible through the social networking system for a pre-determined period of time.

Abstract: In one embodiment, a method includes receiving, from a client system of a first user, an input from the first user indicating a query-domain and one or more query-filters, generating a card cluster comprising a plurality of cards referencing a plurality of objects corresponding to the indicated query-domain and one or more query-filters, ranking the plurality of cards based on one or more user-engagement factors, and sending, to the client system in response to the input from the first user, instructions for displaying the card cluster to the first user, the cards of the card cluster being ordered based on the rankings associated with the cards.

Abstract: In one embodiment, a method includes receiving, from a client device of a user of an online social network, an input from the user to access a card-stack interface, generating a plurality of cards, where each card comprises a suggested query referencing a query-domain associated with the online social network and one or more query-filters, and where each query-filter references one or more objects of the online social network, each card further comprising one or more search results corresponding to the suggested query, and each search result referencing an object of the online social network matching the suggested query of the card; and sending, to the client device in response to the input from the first user, the card-stack interface for display to the first user, wherein the card-stack interface comprises one or more of the generated cards.

Abstract: In one embodiment, a method includes accessing a social graph including a number of nodes and a number of edges connecting the nodes. Each of the edges between two of the nodes represent a single degree of separation between them. The nodes include a first node corresponding to a first user associated with an online social network and a number of second nodes that each correspond to a concept or a second user associated with the online social network. The method also includes generating a number of cards. Each card includes a suggested query referencing a query-domain associated with the online social network and zero or more query-filters for the query-domain. Each query-filter references one or more nodes of the number of nodes or one or more edges of the number of edges.
