"as you sort of imagine IE users as being less tech savvy, more 'used to' clicking on adverts etc."

IE users don't click on adds because they've been conditioned to think long and hard before clicking on anything in IE.

In fact...evolutionary principles state that IE users who are willing to click on any add they see have computers that are so horribly infested with nasty bits, they are unable to do anything useful on the internet.

They've been effectively removed from the internet gene pool...if such a thing exists.
