Claim:
1. A system comprising at least one server computer having at least one processor programmed to: receive, over a network, activity data of a first user measured by an activity monitoring device; process the activity data of the first user to update a value of an activity metric for the first user; responsive to updating the value of the activity metric for the first user, identify a change in an inequality relationship between the value of the activity metric for the first user and a value of the activity metric for a second user, the change in the inequality relationship being defined by the value of the activity metric for the first user changing, from being less than the value of the activity metric for the second user, to being greater than the value of the activity metric for the second user; and responsive to identifying the change in the inequality relationship, trigger, over the network, a first user device to prompt the first user to generate a message to the second user for display on a second user device.
