A system (and corresponding method) is provided that enables virtual spaces to be created based upon user activity and populated with users associated with, interested in or active within the same areas as the user, thus facilitating serendipitous interactions and exchange of knowledge. The system dynamically binds user representations (e.g., avatars, links) into a virtual space that is associated with an activity or topic. Essentially, the system is capable of dynamically gathering or generating representations of users associated with a workflow or tasks within an activity, project or topic thereby enhancing collaboration between users with regard to communications as well as generation and sharing of data.
