Angela mentioned the work Wikia is doing on usability in a thread on Foundation-l. I had a look and, I am impressed. They have a working solution for the problem with templates.
The problem is that many people get frightened off by templates. Compare the screen shot above, a screen shot with a maximum of information on the template used, with the Wikipedia article "Netherlands".
Wikia has at the bottom of each page functionality that allows you to create a new page. This leads to a Special:Createpage. This is a big improvement from the standard MediaWiki method.
Wikimedia Foundation to explore the Wikia code to learn if it is useful. I applaud this. But why wait for the WMF usability project to kick in, would it not make sense for all the people and organisations to start collaborating anyway?
There are many aspects of MediaWiki that need work. There are many people and organisations that will benefit from cooperating.
