Abstract: In one embodiment, a method includes receiving, from a client system of a first user of an online social network, voice input of the first user; receiving, from the client system, information indicating a current geo-location of the first user; parsing the voice input to identify one or more commands in the voice input; determining a data object of the online social network corresponding to the current geo-location of the first user and a command of the one or more commands associated with the current geo-location of the first user; and executing the command associated with the current geo-location of the first user on the online social network, wherein the executed command operates on the data object corresponding to the current geo-location of the first user.

Abstract: In one embodiment, note is received from a first user, comprising a message and a first location. The first location may be specified by the first user. A number of second users are identified based on a respective second location of each identified second user being within a threshold distance of the first location. The message of the note is sent to the identified second users. When the message is sent, it is determined whether a current location of the first user is within a predetermined distance from the first location. If the current location is within the predetermined distance, a notification is sent to the first user informing the first user that the message has been sent to the identified second users.
