Google, Share Prices and Ads

Seeing Google announce quarterly earnings nearly triple their results for the same quarter of last year (they now have an annual revenue of $10 billion, almost entirely from selling ads), it suddenly occurred to me that I have never once deliberately clicked on one of their ads. Sure, I see them often enough, and every once in a while I'll accidentally click on one just because my mouse is in the wrong place, but they're all just noise to me - they don't even enter my consciousness. It goes without saying that I've never purchased anything as a direct result of a Google ad either. This is nothing to do with Google itself either: I'd make the same claim of other internet ad services too.

There's no huge overarching point to this entry; I just wondered out of sheer curiosity whether I was just an oddball anomaly in the statistics, or whether I'm actually in the majority and am pointing out the Emperor's New Clothes. Have you ever deliberately clicked through or even bought something as a result of an internet ad? What percentage of your ad clicks are deliberate versus accidental? If you do click on ads, what catches your eye?
