This is actually pretty cool. Over here in Europe every (most) websites end in a country specific TLD so we know where the website is based. We can see instantly a .fr domain means the website/store is based in France, or .de for Germany, etc and so on. It's not common at all to have a .com for your website.
I suspect in America it's going to be really confusing for people though because as far as I can tell everything is a .com. People probably won't be so keen on adopting a .nyc domain for their NYC based business because everything else is a .com so it might seem lesser or cheap or "not the real thing."
