(Part I, part II, part III, part IV, part V)
There are several interesting trends.
One is growing internationalization of readership. The United States provides the most clicks of any country, and yet that's only 22% of the total! I haven't posted the long tails of these graphs, but they tell the same story: Countries that are in 30th place onward provide a much greater proportion of clicks than they used to.
Two is that the Egyptian click flow has grown from trickle to deluge.
Three is that we have lots and lots of Saudi readers. Especially surprising when you compare relative populations of the top seven countries.
Four is the appearance of a new category of visitor: They are in disguise, hiding their identities behind proxies. In 14th place, they provide 1.5% of clicks.
