A method, system and computer program product for evaluating an impact of a user's content utilized in a social network. Content in a document (e.g., a presentation) that has been posted on a social network environment is detected as being reused by another user in another document. The author of the reused content is then identified. A counter keeping track of the number of times this content has been adopted in derivative works is then incremented. A score (“impact score”), representing the author's ability to influence other users to adopt the author's content in other users' derivative works, is then generated based on the number of times this content has been adopted in derivative works. Social credit is then provided to the author using the impact score. In this manner, recognition is provided to the author thereby providing motivation for users to post created content in the social network.
