The ThomsonReuters impact factor is a viable, widely used and informative measure of journal visibility and frequency of use. It is accurate, transparent and easy to use. It is a live and evolving system, that can broaden its scope and implement new features and methods. Some of Vanclay's suggestions, like wider use of order statistics, or our suggestion of rank normalization might be implemented by JCR in the future.
