Presuming that this circulation more-or-less reflects a reasonable statistical sample of the general population, they're still quite rare.
Hi, David. Good to see you posting here.
It would be a mistake to make the presumption you state. Any survey which suffers as badly as this one does from self-selection error cannot be considered statistically relevant.
In order to be useful, the data has to be gathered from a random and representative sample of the population. It cannot be gathered only by those who are willing to volunteer their data, since that group is necessarily not random. It is also very unlikely to be representative of the population as a whole.
A great many online polls suffer from this difficulty. It is worse than a waste of time to respond to online polls, since it encourages incredibly stupid ideas like voting as a way of taking choices.
