Periods do not work as well in Google for some numbers.

Do you also swap the month and year like most of the rest of the world (7/2/10 instead of 2/7/10) or use only the metric system?

I'd settle for "like the USA does it" since that's where we live.

The USA way for US Residential seems fair to me.
I beats the way nobody expects.
A style choice where the Time Zone and other preferences are, even better!
