I'd much prefer the style of links that wikipedia uses where it is derived entirely from the article title and doesn't rely on the internal ID number.
In my use case this also causes issues. My web application has static links to articles in the wiki, which is serving as a help system. There are several instances of my web application and they each have their own instance of the wiki.
The users can also modify these articles and add new articles. When the user adds their own articles the ids of the articles become unpredictable and when we add new articles to the help system we can't add static links because the ids can now be different for each instance of our web application.
