This is turning out to be an excellent web CMS. I've been looking (frantically searching more like) for a couple of applications to use on the website, an enterprise CMS, a Wiki, and a web CMS. I'm not fond of Mediawiki the syntax is just a bit too strange, this isn't just Mediawiki though it's the wiki syntax. I haven't been able to find an enterprise CMS that actually works out of the box as of yet. This is a different story for a web CMS though, Drupal has been holding a strong first here.
Drupal isn't perfect but it should hold up with no problems. I went back and forth between Wordpress and Drupal a couple of times trying to figure out what it is that I'm looking for. And what about Joomla you ask, it was way more than I wanted to get into and the permissions aren't as fine grained as Drupal.
I've also looked at portals trying to get a grasp of their actual usefulness, JBoss Portal threw too many errors on startup so I never got a chance to go through an evaluation, this was so very frustrating. Liferay was better when I followed the install guide but on my hardware it was just too slow and after playing around for about an hour I couldn't find any good reasons to keep going. I had a couple of problems with a couple of the portlets also, I'm having no luck at all finding something that is actually ready for prime time.
I need to add Alfresco, OpenCms, Magnolia and Nuxeo to this entry also - very disappointing results.
And as far as wikis are concerned, Dekiwiki, PMWiki, Daisy, Tikiwiki and XWiki all failed to impress me.
