I am not necessarily against but I find it a little inconsistent that the Guyana flag would be displayed vertically - even if the country is narrow - while all the other flags are in their normal orientation. Was it making it that difficult? Isn't that the point, to make a little more challenging?
1% is not so surprising, it is low enough. This could be due to 1 in 100 people not being as good in geography and flags as most people on Jetpunk or simply due to a mistake such as skipping the question by accident. 1% is not a high figure.
Thought I was looking at a Norwegian flag for a while at the last one, took me a while and guess for Jan Mayen before a realized it was a UK flag in the corner of another flag, which of coarse turned out to be Fiji.
