What would be the best way to identify countries, both in questions/answers and in tags?
As this is an English-based site, for questions and answers I think it makes the most sense to use the standard English country name, like Brazil instead of Brasil. But how do we handle countries that are typically abbreviated, like The US / USA for "The United States of America"? Should we refer to The UK or The United Kingdom or even Britain or Great Britain?
Tags are generally shorter, so should we stick to the internationally-recognised two-letter country codes? ISO 3166-1 alpha-2 is fairly standard and I think would look quite clean in the tag bar:
