Country-specific leaderboards

We have a global leaderboard; we have City leaderboards on each City page; but what we don’t have is anything in-between. Country leaderboard would be cool if they only count unique streets completed in each country, and would allow international striders such as myself to see how they break down on a nation-by-nation basis. Finally, it would allow (public) striders to identify each other more easily and collaborate or have friendly rivalries over their country-specific pride.
