I second ahpeeyam's point. "...as long as they are getting what they want..." In my surrounding I meet a lot of people everyday who dont even know youtube. Why consider youtube, the address bar... They are clueless as to what to type in. All they know is www.google.com for info. When they search they are happy to find the info they need whether its the link on the right(ads) or left. Most common search keywords have quality advertisers. Now that most ads are of quality the user wouldnt mind clicking on them. We shouldnt be forgetting the fact that these ad matches are displayed according to keywords. When you search for "xyz tv", you might get a CNET review for it in your search results and an ad reading "buy xyz tv at $250". Now the action is dependent on the user. He might either read the review or buy it from the ad link or might even buy it from a search result page that read "at 50% discount" which might be an even better price.
