WordPress is the most popular way for people to build a blog or a website.
WordPress is easy to use and easy to modify. That's why millions of people every day use it to create their own site. Famous users of WordPress include the BBC, the New York Times, Ford and even James Bond.
Joomla! sits half-way between WordPress and Drupal, being both flexible and easy.
Joomla is used by individuals, businesses, and organizations such as General Electric, eBay and the Eiffel Tower. With over 10,000 add-ons available and even more designs, Joomla can do anything you need.
Drupal is powerful, flexible software and is ideal for sites with many features and users.
Drupal is superb at handling more advanced tasks. Many government agencies use Drupal, including WhiteHouse.gov, as do many renowned companies and institutions, such as Sony and the New York Stock Exchange.
