This might to some be old news but at least it's news to me. Sweden has the most Debian developers in the world. ...per capita. In the US they have 283 developers compared to Sweden's 26 only, but Sweden is a much smaller country.
What does this tell us? Nothing much probably, but as a big Debian fan I take great pride in that my fellow countrymen- and women have chosen to work on such a great operating system.
And by the way, have a look at the United States picture. Cool diagram!
