The "auto-detection" features of technology can be great, horrendous, or simply amusing.
Last weekend the Fedora Project held it's winter FUDcon in Toronto. At least one US participant commented in a blog about the amusement of seeing google.ca as they searched for information.
I spent this week teaching at a customer site in the Atlanta area but the parent company headquarters and domain registration is based in Europe. The result is that in addition to google choosing a non-US server for searching, several times when I went to a site and was asked to login or continue the question was not in English.
