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