Internet Explorer users are at least four times as likely to click on Web ads than Firefox users, a German advertising technology company said last week. :(

David Hallowell, a Mozilla contributor, said this trend may have emerged because nontechnical Web surfers, who tend to be IE users, are more likely to click on pop-up ads by mistake, because they think the ad is a system dialog box.

I totally agree with that statement lol, only fools use IE ^_^.
Its really true , remember when the old days we used to surf and used to click on everything we get ? Even now many people click the ads in search engines which they misunderstand for search results. And ofcourse, the more knowledge about the tech side lesser will be the clicks on Ads. Still I think there will be enough newbie’s to click as time goes :p. Ah I just remembered a quote which is a bit similar.

“Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning.” - Rich Cook.
