It was announced that The Whitehouse website is switching from Drupal to, my preferred Content Management System (CMS), WordPress. Which according to the article linked above will provide a more scalable web management solution. It is going to be a big move. The reason for the change is because WordPress provides a seamless backend that can be managed by multiple users and it can provision users’ access across its content easily.
WordPress is used to power almost 30% of the Internet depending on who you ask and where you get your statistics from. Drupal is currently at 2.3%. With WordPress having such wide usage and adoption this means that more people are looking at it, and it is well maintained. Improved security is also important to The WordPress Community and Team since so many websites are using WordPress.
WordPress also offers better discoverability features for search engines. WordPress also offers more updated Plug-ins to offer additional functionality.
I used to design websites in Drupal 2 or 3 years ago. It was great at the time. But in the meantime, WordPress has improved its community efforts, and it has updated its technology, while in my opinion Drupal has stalled. It took a long time for Drupal 8 to come out of beta. During that time WordPress has improved, and become easier to use and update, and keep secure.
