This disclosure provides a system, method, and machine-readable memory for determining various pre-sharing insights and post-sharing insights. The system is configured to receive a request to share content with a first plurality of users represented as nodes in a graph associated with a first user. The system is also configured to determine a second plurality of users selected from the first plurality of users by traversing one or more nodes of the graph. The system further classifies the content to determine a plurality of topics for the content. The system then determines a third plurality of users selected from the second plurality of users by comparing the plurality of topics with user profile attribute values associated with each user of the second plurality of users. The system then communicates a notification to the first user that includes an identification of the third plurality of users.
