The top five countries represented are
USA 25 Chile 11 Argentina, Brazil, UK 6 India 5 Canada 4
My off-the-cuff assumption is the above distribution represents population, location and activity. Although, I must say I am surprised at the under-representation of China, the factory of the world, and unarguably the place where almost all hardware, open or otherwise, begins its life.
I am also happy to note that the institution most participants identify themselve as belonging to is not an institution. Ten of us call ourselves “independent.”
