Abstract: A system for generating and providing an inline resharing interface and sharing content includes a processor and a memory storing instructions that, when executed, cause the system to provide items of content for presentation; receive input identifying a selected item from the items of content; generate an inline sharing interface corresponding to the selected item, the inline sharing interface including a portion of original content from the selected item, an comment area, and an addressee area; and provide the inline sharing interface for presentation in place of the selected item.

Abstract: A system including a processor and a memory storing instructions that, when executed, cause the system to: receive a stream of content including a plurality of content items; retrieve a plurality of related content items; identify a topic for at least one of the plurality of the related content items; rank the topics by relevance to the user and one of the plurality of items; associate the topic to the content item in the stream of content where the topic is ranked as being relevant to the content item; generate a marker for the topic; generate an interface including the marker associated with the content item in the stream of content; and provide the interface for display.

Abstract: Computer-implemented methods for generating and providing a post in a social activity stream by using a post framework and a content framework are provided. The post framework provides clear separation of shared content, the posting user's voice, social metadata, comment discussion, and interactive actions. The content framework includes a defined content body. The content body may include content, metadata and user interface control elements to be provided in a user post within a social activity stream. Systems and machine-readable media for providing a post in a social activity stream by using a post framework and/or a content framework are also provided.

Abstract: A plurality of content items for a content stream is determined by a system. The system estimates size dimensions for the content items, and determines a multidimensional layout by placing the content items into two or more adjacent containers based on the size dimensions. The system determines a difference in size between the two or more adjacent containers and adjusts an aspect of one or more of the content items to substantially equalize a size of the two or more containers.
