Web based content management systems

I am interesting in content management and systems used. Nowadays there are lot of web based cms solutions, but only few can satisfy the real professional requirements with top usability. Here is a list of mostly free common web based blogs, wikis or portal systems i experienced with or at least tested. Most of web server programs written in php language and requires MySQL database server to store the data. The installation is easy and only basic level of webmastering knowledge required or supported by your hosting provider.

• WordPress – personal blog with lot of free beautiful CSS themes
• Drupal – enterprise blog with loth of free themes
• SimpleCMS personal blog
• MediaWiki (php+mysql premium Wiki solution)
• MovableType (enterprise community blog, perl)
• ZenCart, osCommerce (Webshop scripts with customizable templates)
• Mambo, Joomla
• phpNuke, phpBB, bbPhorum
• HTML/OS (CDASite, Web publisher system)
• Zope, Plum (Python based portal system)
