I beg to differ!
If we use EricH's estimates, we would expect 3000/3150 = 95% of all responses to come from North America. Instead, the poll showed 85% of all responses originating in North America.
I don't care to dredge up enough memories of my statistics courses to run the confidence interval on a data sample of this size (that is left as an exercise for the reader), but if anything I'd say that these stats seem to show that CD is skewed towards international teams.
