Google does badly on privacy but it doesn't do well even for its own interest!

Scobleizer complains about Google sucks for travelers. Google puts a little cookie on your computer to track which country your computer is connected, then it will show you the site in the language majority people speak in that country.

If you really pay attention to this statement, there are many places that could break user experience.
Except traveler like Scobleizer, there are many Mexican living in the United States for many years. They don't speak well English. I wonder how they use Google. :)
Google only cares about your computer location, not cares about what language you speak;

If you have been searching porno sites for a night. Second day, you come to office, when you Google something, Google always rank porno sites first since it figures out that might be your best preference.

To be fair, on the first page of Google, there is a link, "preference", which you can use it to change language setting.
