Despite Dan's inability to spell its name correctly, even though it's an Edelman client (forgive him, he's new…), I think the list from Symantec of search terms used by kids online is quite encouraging (though there's no way of telling how old the kids were specifically).
Sure, some people might be aghast that 'sex' and 'porn' appear in the top 10, that 'boobs' comes in at number 28 (kids say 'boobs'? Brilliant!), 'pussy' at 72, 'naked girls' at 86, and 'Playboy' at 93, but how much has it really changed over the years?
I know that all of those search terms were certainly running through my mind as a teenager.
