I use Google's Adsense and I agree with these pointers. Blending in the Ad is always the best tip. Also a good tip is that too much Adsense on a website will hurt too, because you'll decrease traffic and destroy your content.
Very well written Robert. It'll be interesting to see where things go from here. I agree, as things begin to get simpler, and the buying public constantly demands knowledge and faster service, that this gives them that. I agree with #31 Adi above, that this will spark a healthy competition and perhaps innovation, in both the products, and the buying experience.
