Falsehoods US programmers believe about addresses: there are no other countries than the US of A, and if there are, they don’t really matter.
This person bought a whole domain for something that doesn’t work for 90% of the world, claiming it does, never even testing their assumption. Great job!
The name and shame tactic is underrated these days. :)
I don't disagree with you generally but does he really claim it does? The entire page only mentions US, near as I can tell.
