BTW, Dschwen moved the languages to the bottom, although I'm not sure if it's a good idea.
Maybe we should try to detect the language with javascript and offer the choice that we guess is right, with the others hidden under a scroll.
Just added that functionality to Mediawiki:MainPages.js I'm sure it could use a bit more love. A link is added to the Welcome box for anonymous users if the browser language is recognized.
