WordPress is another open source dynamic content management system (CMS) but mostly known as blogging tool. It has many features including a plug-in architecture and a template system. WordPress started as just a blogging system, but has evolved to be used as full content management system and so much more through the thousands of plugins, widgets, and themes, WordPress is limited only by your imagination. By functions it is similar to Joomla and also enables you to build Web sites, publish and manage your content on the Web site easily. Simplicity is secured by the CMS who manages it all. WordPress is completely customizable and can be used for almost anything (news portals, business or corporate sites...), but if you need just a blog it is the best suited for the job. Some features:
WordPress also has a web template system using a template processor where you define design of the Web site. WordPress users may install and switch between themes. Themes allow users to change the look and functionality of a WordPress website or installation without altering the informational content.
One very popular feature of WordPress is its rich plugin architecture which allows users and developers to extend its abilities beyond the features that are part of the base install; WordPress has a database of over 18,000 plugins with purposes ranging from SEO to adding widgets.
Widgets are small modules that offer users drag-and-drop sidebar content placement and implementation of many plugins' extended abilities. Widgets allow WordPress developers to add functionality to their sites. These small widgets can be used to add functionality such as a slideshow, Facebook-like box, small news slider, and more.
WordPress also features user registration system; multi-blogging; multiple authors; integrated link management; a search engine-friendly, clean permalink structure; the ability to assign nested, multiple categories to articles; comments - visitors can leave comments on individual entries; and support for tagging of posts and articles. Automatic filters are also included, providing standardized formatting and styling of text in articles (for example, converting regular quotes to smart quotes). WordPress also supports the Trackback and Pingback standards for displaying links to other sites that have themselves linked to a post or article.
In addition there is of course many more features, and abbilty for developers to build their custom plugins and widgets.
