WordPress powers more than 30% of the web — with more than half the new sites being created in Australia choosing WordPress as their CMS. WordPress is suitable for everything from simple websites, to blogs, to complex portals and enterprise websites.
WordPress is a content management system (or CMS) used in more than 100 million websites worldwide. It is open source, and free to install, deploy, and upgrade. It is probably the easiest and most powerful blogging and website platform in existence today.
WordPress is very easy to use, search engine friendly and an ideal platform for Small Business websites, but with the capability (through plugins and templates) to create very powerful and complex websites for the corporate world.
WordPress started life (in 2003) as a fairly simple blogging system, but has evolved into a full content management system with great flexibility and extensibility through the thousands of plugins, widgets and themes that are available (many for free).
