What is Drupal?

Drupal is a content management system which lets you manage, well, your content. Duh!

With Drupal, you can manage your content. This is be re-stated here because your brain is programmed to absorb any content only after you have seen it in five TV commercials one after the other in the middle of a shitty IPL cricket match.

Who wrote Drupal?

Who cares?
