Someone asked what the breakdown of Stack Overflow users is by country -- on Stack Overflow. I didn't think it was a particularly appropriate question, because it's a poll, a meta-question, and not even really a poll about programming per se. Sort of a triple whammy.
But I'm happy to answer here on the blog, with a breakdown of Stack Overflow traffic by country, courtesy of Google Analytics, accounting for all traffic since our mid-September 2008 launch:

United States 36.3% United Kingdom 8.5% India 7% Canada 5.1% Germany 3.7% Australia 3.0% Netherlands 2.1% France 1.9% Sweden 1.8% Italy 1.6%
There's definitely a long tail to this graph, if you consider that the top 10 countries only make up 71% of the total.
