Does for example google use this in searches now? Lately I've noticed 
that my searches return things that are close to me or at least in 
Finnish language. Perhaps they just use the language information. 
Sometimes it's good to find things that are close but in the long run 
that might distort my world view, especially if the search engine does 
not tell me what it does.
