Abstract: Systems, methods, and non-transitory computer-readable media can provide a messaging interface that includes at least an option for sending ephemeral messages to users of a social networking system and an option for sending non-ephemeral messages to users of the social networking system; and send a message through the social networking system, wherein the message is sent through an ephemeral message thread or a non-ephemeral message thread as designated by a user operating the computing device.

Abstract: Systems, methods, and non-transitory computer-readable media can provide a messaging interface, the messaging interface including one or more options for accessing at least one unified message thread, wherein both ephemeral messages and non-ephemeral messages are exchanged between a group of users through the unified message thread. A determination can be made that a user operating the computing device has created a message to be sent through the unified message thread. The message can be provided for distribution to the group of users through the unified message thread.

Abstract: Systems, methods, and non-transitory computer-readable media can provide a particular map portion out of a plurality of map portions representing a particular region. An instruction to zoom in, to a requested zoom level, with respect to the particular map portion can be received. It can be determined that a set of four map portions for representing the particular map portion at the requested zoom level is yet to be available. The set of four map portions for representing the particular map portion at the requested zoom level can be acquired. An enlarged version of the particular map portion can be provided, based on the requested zoom level, as a preview for the set of four map portions. The enlarged version of the particular map portion can be provided while the set of four map portions is being acquired.
