Providing dynamic, interest-based change notifications includes detecting an event for an artifact managed by a collaborative system, determining a user subscribed to the artifact, and, responsive to the event, calculating a score for the event using a processor. The score is user-specific and indicates a level of interest of the user for the event. The score is compared with a threshold score. A change notification of the event is sent to the user responsive to determining that the score exceeds the threshold score.
