WordPress
WordPress is an open source blog publishing application created using PHP and MySQL. WordPress can also be used for a basic content management website. However through the existence of thousands of plugins, widgets, and themes WordPress can offer so much more.
WordPress´s templating system can be changed without editing PHP or HTML code, as well as themes which can be installed so you can easily customize your site. If you have a basic knowledge or understanding of PHP and HTML you will be able to make your own customizations to these themes. WordPress also features integrated link management; a search engine-friendly, clean permalink structure; the ability to assign nested, multiple categories to articles; and support for tagging of posts and articles. Automatic filters that provide for proper formatting and styling of text in articles (for example, converting regular quotes to smart quotes) are also included. WordPress also supports the Trackback and Pingback standards for displaying links to other sites that have themselves linked to a post or article. Finally, WordPress has a rich plugin architecture which allows users and developers to extend its functionality beyond the features that come as part of the base install.
At time of writing WordPress is at version 2.9.2
