Hoi,
There has been a lot of controversy about language support. Some of the arguments used indicate a lack of understanding what it is language support does. In my opinion language support is a primary requirement of MediaWiki. MediaWiki supports languages really well.
In a blog post [1] I have written what language support is about and, I have indicated where Wikimedia engineers and developers are involved.
What I hope to achieve is some clarity on this subject. When you find anything to add or have comments I really want to know.
One final consideration, English is not even 50% [2] of our page views. Thanks, GerardM
