Small business website, it's easy and affordable.
Drupal as CMS has a very large, active community. Instead of focusing on blogging as a platform, Drupal is more of a pure CMS. A plain installation comes with a ton of optional modules that can add lots of interesting features like forums, user blogs, OpenID, profiles and more. It's trivial to create a site with social features with a simple install of Drupal. In fact, with a few 3rd party modules you can create some interesting site clones with little effort.
One of Drupal's most popular features is the Taxonomy module, a feature that allows for multiple levels and types of categories for content types. And you can find plenty of professional Drupal Themes, which are ready to be customized and worked with. You can also grab Drupal Plugins.
Drupal also has a very active community powering it, and has excellent support for plugins and other general questions.
You can also hire a developer to complete a range of tasks for your Drupal site for a reasonable fixed fee.
Drupal is our go to CMS as it is very secure.
Wordpress blogging platform is far and away the most popular CMS for blogging, and probably the most popular CMS overall. It's a great platform for beginners, thanks to their excellent documentation
and super-quick installation wizard. Five minutes to a running CMS is pretty good. Not to mention the fact that the newest versions auto-update the core and plugins from within the backend, without having to download a single file.
For those users not familiar with HTML or other markup language, a WYSIWYG editor is provided straight out of the box. The backend layout is streamlined and intuitive, and a new user should be able to easily find their way around the administration section. Wordpress also comes with built-in image and multimedia uploading support.
The WordPress Community is a faithful and zealous bunch. Wordpress probably has the widest base of plugins and themes to choose from.
A great part about the Wordpress community is the amount of help and documentation online you can find on nearly every aspect of customizing WordPress. If you can dream it, chances are it's already been done with WordPress and documented somewhere.
