Amen to that.
Remember, we look at it from an "improving organic search results to benefit users worldwide and offer them the right service and/or information they seek".
Google looks at it from a "make the search results look at least like we tried and make sure the adwords ads are as bright and shiny as possible".
All the ideas you're coming out with are quite good and would probably really help create a brilliant organic search engine ... but Google isn't into that anymore. Someone should trawl this thread, create a search engine based on that and charge a subscription to use it. I would pay if it meant I could actually find things on the web for once and be guaranteed that the page won't be covered with eBay affiliate ads .....
