It'd be fun to see this for the whole world. It would also make it easy to compute the answers to common quiz questions involving doubly landlocked countries, countries with most borders, etc.
There seems to be some sort of issue with Twitter whereby the javascript to fetch/render the tweet doesn't fire if you open it in a background tab and then visit the tab.
Refreshing the page causes the javascript to correctly fire and the tweet is displayed. This is due to Twitter no longer pre-rendering the page server side, its all done client side.
Also makes it impossible to use Twitter from a browser with javascript disabled.

And this time I checked, it's accessible. Must have been a transitory glitch.
Thanks.
