Abstract: An online system provides a continuous feed of content items to a client device. The online system maintains an ordered set of ranked content items for sending to the client device. The online system receives requests from the client device for content items and selects a subset from an ordered set of ranked content items in response to each request. The number of content items in the subset may be based on factors such as the network connection strength of the client device. The client device re-ranks content items received from the online system based on information received during a given session. The session information may indicate the types of content items viewed during the given session, or the speed at which the user is viewing content items during the given session.

Abstract: Systems, methods, and non-transitory computer readable media are configured to subscribe a subscriber to a content item appearing at a first position in a news feed of content items based on selection of a setting to subscribe to the content item. A pop up window including a response associated with the content item on a user interface displayed by a computing device associated with the subscriber is presented to the subscriber based on posting of the response. Scrolling of the news feed in response to user inputs is concurrently presented on the user interface while the pop up window is presented. At least one selectable setting to dismiss the pop up window from view on the user interface is provided. In response to dismissal, the content item assumes the first position in the news feed or assumes a second position in the news feed based on a re-ranking.
