Yup. From the query I did yesterday I got it's 357 users whose location after conversion to uppercase reads PLANET EARTH (51st most popular) ;) Higher is WORLDWIDE (778 users, 19th position) - right above my country's English name (POLAND, 735 users).
Another thing is USA is 2394 (5th), US - 664 (24th), CALIFORNIA - 728 (22nd), TEXAS - 486 (33rd) and few other US locations that have no "United States" in it's name, yet are used by more people.
Most common location that is not a country name is at 8th (ACEH, 1723 users), while INDONESIA is 6th with 2349 users). Most common city - LONDON with 1046 (14th), right behind UK (1108, 13th).
@ekonugraha - interesting blog entry nonetheless. Inspired me to take a look at user's statistics myself and also arcange's blog.
