WordPress › Google XML Sitemaps � WordPress Plugins: Author: Arne Brachhold
This plugin will create a Google sitemaps compliant XML-Sitemap of your WordPress blog. It supports all of the WordPress generated pages as well as custom ones. Everytime you edit or create a post, your sitemap is updated and all major search engines that support the sitemap protocol, like ASK.com, Google, MSN Search and YAHOO, are notified about the update."
This could be a big deal. The easier it is to get from wiki's and blogs to the web, the better life will be for all of us.
