It's good to see the market still evolving, and that Google doesn't have the one final solution yet. This could lead to a multi-tier advertising system, where brand names and their money trade with each other, and lesser known (or financed) brands use G! or Y! to connect them with non-brand sites. This probably works against the small site operator, as you could soon only have access to the lower paying advertisers, unless you can really impress in your niche.
