We've installed a tracking tool (Google Analytics) in the footer code of the wiki-template to allow us to get a better idea of who travels where on the wiki, where they come from, and what language they speak. This is really important to us because it allows us to change how our visitors see our content. Ideally having this information will allow us to improve the browsing experience of the wiki overall.
