Just to respond to some misinformation floating around out there in the Drupal world. There is actually little difference between Drupal and Joomla these days. If anything, Joomla is growing faster than Drupal in adoption, interest, and usage. The amount of development for 3rd party extensions is stunning. Neither Drupal nor Joomla are going anywhere anytime soon, but Joomla is clearly the future-forward choice now that 1.5 stable has been released.

Responding to a colleague of mine from October 2007:

Editing in Joomla is as simple as logging in, clicking a pencil icon, making your changes, and saving. The end.

With the right editor (we strongly recommend wysiwyg pro and install it for all of our clients) , uploading/insert images, files of all kinds, linking to internal/external pages, it's all a breeze. The wysiwyg pro plugin is available for both Joomla and Drupal, by the way.

Sections and categories are not required for content in Joomla 1.5, as he alludes to in his post. We strongly recommend them because they make finding pages to edit easier from the back end. They also facilitate some fairly sophisticated ways of sorting and displaying data within Joomla.

So don't let "ease of editing pages" keep you away from Joomla. Remember that technology is a moving target, and the Joomla developer community is keenly aware of what needs improving, and they are constantly moving towards improving the software.
