Why WordPress as a CMS?
It’s extremely easy to use. It’s open source. There is no cost per user/seat licensing.
It has a Simple Visual Editor or Text Editor with HTML support. 
And now it also has an amazingly simple yet powerful image management capability as well.
Of course with its blogging roots, WordPress has incredible blogging and socialization capabilities built in and ready to go.
In our opinion, WordPress as a CMS is in a class by itself. It was designed for users to publish content. It has more plugins (29,265) available than any other CMS system. Other systems such as Drupal and Joomla are really frameworks targeted at web developers first and users second. Drupal in particular is said to be “more difficult to learn and understand”.
