Wordpress is a content management system (CMS) that is better than other CMS options like Joomla, Drupal, and Expression Engine. It has a user-friendly backend interface designed by usability experts. Wordpress powers over 4 million blogs and is very customizable through plugins, templates, and custom fields. While custom fields provide flexibility, they have limitations like a lack of WYSIWYG editing. Relationships between custom fields can also be difficult for users to manage. Future improvements could include custom post types and interfaces for selecting related posts.
