The method of claim 1 , wherein identifying one or more differences between the activity information associated with the former subscriber of the social network service and the activity information associated with the current subscribers of the social network service includes identifying an activity that was performed by the current subscribers of the social network service during an initial subscription time period and was not performed by the former subscriber of the social network service during the initial subscription time period; and

wherein performing an action based on the identified one or more differences between the activity information associated with the former subscriber of the social network service and the activity information associated with the current subscribers of the social network service includes performing an action associated with causing the former subscriber to perform the activity.

4. The method of claim 1 , wherein identifying one or more differences between the activity information associated with the former subscriber of the social network service and the activity information associated with the current subscribers of the social network service includes identifying an activity that was performed at a certain performance level by the current subscribers of the social network service during an initial subscription time period and was not performed at the certain performance level by the former subscriber of the social network service during the initial subscription time period; and

wherein performing an action based on the identified one or more differences between the activity information associated with the former subscriber of the social network service and the activity information associated with the current subscribers of the social network service includes performing an action associated with causing the former subscriber to perform the activity.

5. The method of claim 1 , wherein the former subscriber and the current subscribers of the social network service are members of a same professional group within the social network service.

6. The method of claim 1 , wherein comparing the accessed activity information to activity information associated with current subscribers of the social network service includes comparing a number of searches performed by the former subscriber within the social network service to an average number of searches performed by the current subscribers of the social network service.

7. The method of claim 1 , wherein comparing the accessed activity information to activity information associated with current subscribers of the social network service includes comparing a number of profile views performed by the former subscriber within the social network service to an average number of average profile views performed by the current subscribers of the social network service.

8. The method of claim 1 , wherein comparing the accessed activity information to activity information associated with current subscribers of the social network service includes comparing a number of messages sent by the former subscriber within the social network service to an average number of messages sent by the current subscribers of the social network service.

9. The method of claim 1 , wherein performing an action based on the identified one or more differences between the activity information associated with the former subscriber of the social network service and the activity information associated with the current subscribers of the social network service includes presenting the former subscriber with a recommendation to perform an activity via a profile page associated with the former subscriber within the social network service.

10. The method of claim 1 , wherein performing an action based on the identified one or more differences between the activity information associated with the former subscriber of the social network service and the activity information associated with the current subscribers of the social network service includes presenting the former subscriber with a recommendation to perform an activity via a direct message from the social network service to the former subscriber.

11. A system, comprising:

a processor for executing instructions stored in a memory device;

at least one memory device storing instructions, said instructions collectively forming modules, the modules including:

an information module that is configured to access information associated with a former subscriber of a social network service, wherein the former subscriber is a non-subscriber user of the social network service;

a comparison module that is configured to compare the accessed activity information to activity information associated with current subscribers of the social network service;

an identification module that is configured to identify based on a weight assigned to activities of the activity information associated with the former subscriber and the activity information associated with the current subscribers one or more differences between the activity information associated with the former subscriber of the social network service and the activity information associated with the current subscribers of the social network service; and

an action module that is configured to perform an action based on the identified one or more differences between the activity information associated with the former subscriber of the social network service and the activity information associated with the current subscribers of the social network service, wherein the action comprises causing a portion of a webpage to be displayed on a screen of the former subscriber of the social network service to prompt the former subscriber to perform an activity to reduce the one or more differences between the activity information associated with the former subscriber and the activity information associated with the current subscribers.

12. The system of claim 11 , wherein the identification module is configured to identify an activity that was performed by the current subscribers of the social network service and was not performed by the former subscriber of the social network service; and

wherein the action module is configured to perform an action associated with causing the former subscriber to perform the activity.

13. The system of claim 11 , wherein the identification module is configured to identify an activity that was performed by the current subscribers of the social network service during an initial subscription time period and was not performed by the former subscriber of the social network service during the initial subscription time period; and

wherein the action module is configured to perform an action associated with causing the former subscriber to perform the activity.

14. The system of claim 11 , wherein the identification module is configured to identify an activity that was performed at a certain performance level by the current subscribers of the social network service during an initial subscription time period and was not performed at the certain performance level by the former subscriber of the social network service during the initial subscription time period; and

wherein the action module is configured to perform an action associated with causing the former subscriber to perform the activity.
