A method, system and computer program product for improving the engagement of the user in collaboration activities. A collaboration mechanism detects a request to select an artifact (community, file) by a user in a communication system. The collaboration mechanism analyzes the communication system for collaboration activities (e.g., postings) related to the selected artifact to determine a list of related artifacts. The collaboration mechanism then determines the collaboration activities for each artifact in the list of related artifacts. The collaboration mechanism then analyzes the determined collaboration activities for each artifact in the list of related artifacts to form a collaboration summary (summary of the collaboration activities) for each artifact which is presented to the user. As a result of presenting such a collaboration summary to the user, the user is more likely to engage in collaborative activities with other artifacts since they are related to the artifact selected by the user.
