Stomme, why google.us and not google.nl? Is it just because "Google us" sounds like google are talking to you?
Google.nl is so concerned with giving me more Dutch results that it means I miss out on better results related to my queries, which 99% of the time are not Dutch-related.
google.us usually brings me to google.com. Google.com I cannot type in without getting google.nl. Since google is American, google.us == google.com
