Hey Joe,
This article (http://news.bbc.co.uk/1/hi/technology/5286458.stm) got my concern. Editorial control on the Wikipedia? What exactly have I missed?
The article discusses two changes, one in past and one in present tense. The old change, mentioned as a reaction to the Siegenthaler[0] bizzo, was "recent changes make it harder for ordinary users to create and update pages on the site." This obviously refers to banning new-page creation from anons[1] and semi-protection[2].
The more recent change, preventing anon users (I assume) from creating pages or making edits until they're approved by someone else, is something the author asserts the German Wikipedia are experimenting with. However, given that it's been discussed repeatedly here, it's not unreasonable to assume, as the author does, that if the German trial goes well, we might adopt it, too.
[0] If I get it wrong this time, it's the BBC's fault.
[1] Much as I like the lower workload this has caused, it might be nice to new page creation back on and see what happens. We can even call it an "experiment", if only to see how Bryan Derkson reacts ...
[2] Indeed, he mentions semi-protection explicitly later on.
