The website of the Hula project, recently announced by Novell (Ximian), is powered by MediaWiki (the Wiki software developed for the projects of the Wikimedia Foundation). The Mono project website, also hosted by Novell, has just been migrated to MediaWiki. Is this creating a new tendency (the use of Wiki-like sites instead of more classical, centrally administrated, CMS software), or is just a concrete decision for a couple of related projects.
What’s the real difference between wiki software (MediaWiki, Twiki), and more “classical” CMS software (Drupal, eZ Publish). Couldn’t we configure the Twiki in order to imitate a standard Drupal configuration? Wouldn’t we be able to configure eZ Publish with a template such that any published story has an Edit button immediately connected to the form where we can modify that story? In the end both approaches are developing content management software, and the key differences are: the ease of installation, configuration (how far away is the standard configuration from what we need) and use; the support for a lot of concurrent users (performance), and the features provided by the available modules (potential functionality).
And the fact is that probably all kinds of CMS software are moving towards some mix of functionality that is a closure of the features of all of them in their origin.
