Says the official announcement:

Drupal is a powerful publishing and content management system. Users can add all sorts of content to Web pages through a system of modules. The software itself is free and open-source; users need simply pick out which site elements they want, and then put them together.

Drupal has been used on several popular and professional sites.

...including PopSci.com.

Apparently nearly 2 million votes were cast.

This is not the first time Drupal has won this honor. This is why pingVision develops almost all of its web-based projects using Drupal. There simply is no other content management system or application framework, open source or not, we'd rather work with for enterprise-level websites.

This news comes hot on the heels of Business Week's naming Drupal founder Dries Buytaert as "Innovator of the Year".

Drupal has been around for a while. It's nice to see it -- and Dries -- receiving their due.
