farmboy, that's what I was getting at. I think that since many of us earn income both from affiliate programs and from advertising programs such as AdSense, the distinction between them can get blurry. But with an affiliate program, we can (and do) push a particular product as hard as we want, give it as much space on our site as we want, etc. We are trying to sell it. With AdSense, we are prohibited from drawing attention to the ads, never mind trying to sell something that appears in an ad. What we are being paid for is the advertising space.
