It's a good question.

This is almost certainly the cause.

I don't think this is visible to the page currently, except indirectly 
via navigator.language, so if your browser is configured to only report 
English, that's all the page should see.


The feature requested in this thread did end up being added to the spec:

   http://whatwg.org/html#language-preferences

It's basically just an array version of navigator.language, and the spec 
suggests using the same list as for Accept-Language, so it doesn't really 
provide anything new, it's just more convenient.

It's true that Accept-Language doesn't seem to have been widely used. The 
feature was primarily added due to requests from implementors. I don't 
know what we can do to cause authors to rely on this API and its siblings 
rather than on IP geolocation.
