Most Pop-Up Click Throughs Are Accidents

Techdirt links to a story about a study that indicates that up to 90% of all pop-up ad click throughs are accidental.

And the other 10% all have x10 cameras aimed at their 4ug3 Manh00!!d even as we speak.

Probably not, but I have to wonder if that other ten percent isn't "accidental" because the ads themselves are designed in such a fashion as to deceive the user into clicking through with a jpeg close button.
