Very few people beyond our direct community are aware of the existence of links to particular versions of any given page - on the English Wikipedia, the "Permalink" option is squirreled away in the Tools section of the navigation bar on the left. The word "permalink" itself is even jargon. I think the future interface for MediaWiki would benefit readers of all types by offering somewhere an obvious and simple point of provision of a permanent link to whatever page is being currently viewed.
