This really needs a cartoonist. I thought I should grab it before it gets changed.
“The BBC was surprised by the lack of response to its latest Internet survey”
The serious point: now you have another reason not to trust web surveys.
Update: The BBC’s form is not completely daft: it says “at home” and you might be on the Internet at work or in a café. Still, that’s going to be unrepresentative of the 30% – it is exactly the sub-set which is already proven to be Internet users, whereas we most want to hear from those who are not and need to be “persuaded to go online”. Thanks to @rupertg and @putsimply on Twitter for the correction.
