Drupal is a CMS (content management system). It is basically a website in a box. When comparing Drupal between Joomla, Drupal wins. The development is further along in regards to useability and stability. I do not believe any CMS is without its learning curve, so I suspect that is why most folks use WordPress as a simple CMS, but Drupal would be the next step up. That said if you are willing to put a little bit of time aside, learning Drupal will not kill you (metaphorically speaking).
