A poll that extrapolates 26,492 respondents with Internet access to all humans is, to me, not to be accepted lightly, as it shows an intention of making themselves bigger than they are.
And I would like to point that the countries that "lead the way" are Russia, Mexico and China.
PS: Portugal was not included in that "research" (I suppose) because we don't have enough "Internet penetration". The only African country included was South Africa.
