Originally designed as a blogging platform, WordPress has evolved into a fantastic system for publishing all manner of content. Whilst it is not quite as flexible as Drupal, it is far easier to use, and has a great variety of high quality themes, making it relatively easy  for anyone to build a website. If you have your own server or hosting, you can download and install a copy of the software within 5-10 minutes. With such a setup, you have are afforded great flexibility in terms of site setup and content. Alternatively, you can use the free hosting service provided at www.wordpress.com, which uses the same platform, but applies controls on content and functionality.

I like WordPress so much that I used it in the creation of this website.
