Issues of notification and awareness have become increasingly important in CSCW. A taxonomy of the design space for notification servers is presented, based on theoretical results from status­event analysis. This provides a framework and vocabulary to compare and discuss different notification mechanisms and thus improve design. The paper shows that notification servers are often ideally placed to provide impedance matching providing an appropriate pace of feedthrough for the user, allowing them to see changes to shared objects in a timely manner. Finally, the paper describes GtK (Getting to Know) an experimental notification server currently being extended to support impedance matching.
