Why is it that nobody cares about the fact that web browsers can send the preferred locale to a web server?

I like Google, but the way they handle this is just horrible.  Yes, there are workarounds, but I don’t need a web site detecting what language I am interested in.

The latest site with this habit that I noticed is IMDB: Browsing it in Germany leads to the comical situation where the site content is in English but the Movie Titles are in English.  This doesn’t make ANY sense.  Yes, there is a workaround too (create an account, set the language in the settings), but this is just stupid.

The sad thing is that this won’t improve any time soon.
