Re: For once, I agree with FaceBook.
So they will have to show the name "GezichtBoek" for the Flemish speakers of Belgium and something else for the French speakers.
As an organisation in Belgium you really don't want to annoy either language group in Belgium by persistently presenting them with the "wrong" version of your website. So that will present an interesting technical challenge for FaceBook if they are not allowed to set cookies in a user's browser.
The old adage "Be careful when you wish for something" springs to mind...
