A method, system and computer program product for handling notifications. A notification system monitors content (e.g., photograph) followed by a user for updates on a communication system. If the notification system identifies updates to content out of the monitored content, then the notification system applies the policy for delivering notifications concerning the content followed by the user that was updated. The notification system registers to receive information about updates to the content followed by the user as well as new events on the communication system. In response to identifying updates to content related to the content followed by the user that was updated from the received information, a summary concerning the updates to the content followed by the user and the related content is then generated. A notification is then delivered to the user containing the generated summary in a manner consistent with the policy.
