No matter how long you keep a web site, if you update it frequently, holding a community, or taking care of it in any other way, at any moment idea of changing or improve its functionality may come to your mind.

He also includes a few links to some of the larger CMS extension sites for Drupal, WordPress, Blogger, Joomla and DotNetNuke.
