Abstract: Uses of an online system include a target user and other users that are connected to the target users. The online system presents a content item received from a target user to the other users. The online system receives comments on the content item from the users and a selection of one of the comments from a user. The online system provides one or more types of actions (e.g., adding the comment to the content item or highlighting the comment) on the comment that the user can take. Upon receiving a selection of adding the comment, the online system modifies the content item to include the comment. Upon receiving a selecting of highlighting the comment, the online system associates a highlighting feature to the comment. The online system provides the modified content item or highlighted comment for display to the plurality of users.

Abstract: An online system receives a request from a target user to present a poll to other users of the online system. The poll includes a question and answer options associated with the question. The online system provides the poll for display to the other users and receives a selection of an answer option from each of the other users. Also, the online system receives comments associated with the poll from some of the other users. The online system qualifies the comments. For example, the online system generates a comment group for each of the answer options that includes comments from users who selected the answer option. As another example, the online system generates an indication for each comment that shows which answer options was selected by the user having provided the comment. The online system provides the comment groups and/or answer indications to the target user and the other users.

Abstract: A social networking system enables users to interact through a content item in real time by presenting an interaction bar to a user viewing a content item page associated with the content item. The social networking system presents the content item pages for content items along with a content item header. The content item header remains at a fixed position on the display of a viewing user's client device at the top of the display. If the social networking system receives an interaction with a content item, the social networking system can identify users who are viewing the content item page associated with the content item and present an interaction bar that describes the interaction in the content item header. To determine whether to present an interaction bar to a viewing user, the social networking system can calculate an affinity score of a viewing user for the interaction.

Abstract: In one embodiment, a method includes accessing a media item associated with a first user of a social-networking system and determining an interest associated with the first user. The method also includes receiving, from the first user, a selection of a user experience modification for the media item, wherein the user experience modification is associated with the determined interest. The method further includes applying the selected user experience modification to the media item associated with the first user.

Abstract: In one embodiment, a method includes accessing, from a data store of the communication network, user information associated with a first user of the communication network, identifying one or more entities associated with the communication network that are relevant to the first user based on the user information, and retrieving, for each identified entity, one or more content frames associated with the entity. The method includes ranking the one or more content frames based on the user information. The method also includes sending, to a client device of the first user, one or more of the content frames for display to the first user in ranked order, wherein each content frame is selectable by the first user to display the selected content frame in association with a particular content item for a specified period of time.

Abstract: A receptacle for a key comprises a casing defining an interior space for receiving a key. The casing is formed at one end with an opening through which the key can be introduced into the interior space, with its operating portion first, and at its opposite end with an opening large enough to allow the operating portion of the key to project therethrough while the gripping portion of the key remains in the interior space. The casing has a main face which is formed with a slot-form opening extending substantially the entire distance between the opposite ends of the casing.
