n: to mean "best neutral view]] is very appealing. It would replace w: and would open the possibility of using Metaweb or another Wikipedia even, like Simple English Wikipedia. In fact the lookup could be per article with some hacks to the code. Though mediawiki will never do this, it being under the control of fascists, it seems easy to do it in tikiwiki or MoinMoin, which are far better candidates for the Content Wiki anyway.
