Drupal is a content management framework, content management system and blogging engine which was originally written by Dries Buytaert as a bulletin board system. Drupal has become much more, thanks to its flexible architecture, and is the software used to power Debian Planet, The Onion, Terminus1525, TPM Cafe, Nerdshift, Spread Firefox, and KernelTrap, among others. Drupal is written in PHP using strict coding conventions. As of May 9th, 2006, the current version is 4.7.

Drupal is what you need to use to build anything from a static homepage, to a fully-fledged,

customizable, and interactive website in several languages, with tens of thousands of users all over the world.

Drupal is capable of much more than blogging, but it certainly has enough to offer as blogging software for most of us.  In particular, if you are just starting with the development your personal site, Drupal will allow you to start as a simple blog while building a much more extensive site around it.

There's a lot happening in the Drupal community. Most notable is probably the recent release of Drupal. A lot of the features tlots of users have been begging for have been added this time. It's making steady progress with each new release, something we can all appreciate.

In addition to that, it is still free!
