Nathan, I think there will always be a good amount of non-converting clicks for various reasons and it is something that needs to be budgeted for. Whether the ad is clicked by accident or whether it is being used as a tip jar, it is just a reality of the PPC world.

Alika, as far as adblindeness goes, I don't think people will become completely blind to adsense ads. For the most part, adsense ads are high quality. They are relevent and in many cases add value to the user.

It is in the advertisers best interest to accurately describe their site or service, because it will increase their conversion rate. And as long as ads are being placed where they serve the user, I don't beleive that the rate of adsenseblindness will increase to levels where they will destroy the adsense program.

It is only if the user is repeatedly betrayed that he will begin to ignore this type of advertising. Which doesn't seem to be happening yet.
