I don't like the change to include an uselang parameter. I prefer the language I've selected in my preferences to be used.
Including this parameter also has undesirable side effects. For example, when you use a link like Beginners' guide or ES:Beginners Guide to get to a page, it will not show the current language in black and bold font, but instead it will display a link as usual (that's because the link's target is different from the current page: it includes the uselang parameter while the current page's url does not). Also, printing a page is negatively affected by the listing of urls with uselang parameters: . --Tordanik 16:09, 22 November 2009 (UTC)
