Dynamically-sorted contact information

1. A method comprising:

by one or more computing devices, accessing for a first user contact information of a plurality of second users, wherein the first and second users are users of a social-networking system comprising a graph comprising a plurality of nodes and edges connecting the nodes, the nodes comprising user nodes that each correspond to a user of the social-networking system, there being a node in the graph corresponding to the first user, there being a node in the graph corresponding to each of the second users;

by at least one of the one or more computing devices, determining a current use by the first user of an application for accessing contact information;

by at least one of the one or more computing devices, determining, for at least one of the second users, a current use by the second user of the application;

by at least one of the one or more computing devices, determining a current location of the first user and a current location of the second user;

by at least one of the one or more computing devices, determining that at least one of the second users is not a contact of the first user;

by at least one of the one or more computing devices, dynamically sorting the contact information of the second users by giving preference to contact information of:

at least one second user for whom a current use of the application occurs during a time that the second user is determined to be at the same location as the first user, and

the at least one second users determined not to be a contact of the first user;

by at least one of the one or more computing devices, re-sorting the contact information of the second users in response to a determination that at least one of:

at least one second user's current use of the application;

at least one second user's location;

the first user's current use of the application; or

the first user's location

changed by a predetermined amount; and

by at least one of the one or more computing devices, providing the contact information of the second users as sorted for display to the first user.

2.

preferences;

plans;

emotional state;

interactions with a network; or

individuals or entity in the proximity of the first user's location.

6. The method of claim 1 , wherein dynamically sorting the contact information of the second users comprises sorting based on a degree of similarity between the use of the application by the first user and the use of the application by the second user.

7. The method of claim 1 , wherein the current use of the application by the first user and the current use of the application by the second user comprises opening the application.

8. One or more computer-readable non-transitory storage media embodying software that is operable when executed to:

access for a first user contact information of a plurality of second users, wherein the first and second users are users of a social-networking system comprising a graph comprising a plurality of nodes and edges connecting the nodes, the nodes comprising user nodes that each correspond to a user of the social-networking system, there being a node in the graph corresponding to the first user, there being a node in the graph corresponding to each of the second users;

determine a current use by the first user of an application for accessing contact information;

determine, for at least one of the second users, a current use by the second user of the application;

determine a current location of the first user and a current location of the second user;

determine that one of the second users is not a contact of the first user;

dynamically sort the contact information of the second users by giving preference to contact information of:

at least one second user for whom a current use of the application occurs during a time that the second user is determined to be at the same location as the first user,

and

the at least one second users determined not to be a contact of the first user;

re-sort the contact information of the second users in response to a determination that at least one of:

at least one second user's current use of the application;

at least one second user's location;

the first user's current use of the application; or

the first user's location

changed by a predetermined amount; and

provide the contact information of the second users as sorted for display to the first user.

9. The media of claim 8 , wherein the software is further operable when executed to dynamically sort the contact information of the second users based on one or more contemporaneous attributes of the first user, the one or more contemporaneous attributes of the first user comprising information describing one or more of the first user's:

preferences;

plans;

emotional state;

interactions with a network; or

individuals or entity in the proximity of the first user's location.

10. The media of claim 8 , wherein the software is further operable when executed to dynamically sort the contact information of the second users based on one or more contemporaneous attributes of one or more of the second users, the one or more contemporaneous attributes of each of the second users comprising information describing one or more of the second user's:

preferences;

plans;

emotional state;

interactions with a network; or
