I don't want to be rude and call anyone ignorant or dumb, but which audience(s) seem to be the ones that click the most ads? Older women? Women in general? Teenagers? Parents who are extremely unfamiliar with the internet as a whole? What are your opinions and experiences?

I saw a comment that Will left on a thread, that basically stated people in the tech area are pretty blind to ads. I'm blind to ads. I only notice them because I am also using adsense on MY sites. Otherwise I wouldn't even bat an eyelash. (Also helps that I use adblock plus.....)

Who do you think is most likely to be the LEAST "ad blind"?
