I can agree with that list. Although I would put a few more American cities in there.

El Chinito nailed it. Friendly city means a place where the locals cater to tourist crowds. Happily take their money and send them on their way with a smile and a wave.

To me friendly means just being open to social interaction with strangers. For this reason America and Australia are the top.

And yeah, Glasgow is still one of the friendliest cities I have been to.
