In "Tune It Up, Don't Tear It Down: Website Redesigns", the author made the case that sometimes a "redesign" may be too radical a solution to a Web site's problems and suggested a number of "tune-ups" to improve a site without tearing it down and starting over. An underlying theme to the tuneup approach is that redesigns are disruptive for both you and your users. Many of the Web's landmark properties change very little, or at least very subtly, over time. Take Amazon: Its Web site of 2009 does not look a whole lot different from the Amazon of 2000. Instead of designing your site so that it degrades gracefully in older browsers, design it with progressive enhancement in mind. The two formats share the goal of making pages look and work properly in old browsers, but they take different approaches.
