The virtual space and its inhabitants is explicitly designed to facilitate this. Techniques of 'interest based navigation' bring together those virtual agents whose interests are likely to fit into a productive social process. Their interactions accumulate an information context, mined from a variety of structured and unstructured sources, and related to the different interests involved. At all times, techniques of 'competition for attention' focus the interactions and in particular the stream of information towards the user. You can see the weareable quite well to on the photo.
