Modern Page Ranking problem

Google rely on content inside the pages but do not rely on representation information on the page. It was great idea to implement Page Rank, but it’s ranked by a machine so it can only basically choose which content is good and which is not. But what about of graphical impression and overall site usability? Machine can’t rank usability and user experience value. Only user can do that.

My idea is to allow web users to rank the page they see. We must reinvent browser standards and implement not only “Back” and “Forward” buttons but also a “Good” and “Bad” buttons that will allow users to rank a page they actually see. It doesn’t matter if they came to the page from a search engine or directly – they shold have ability to contribute their opinion on a web page!
This data will be collected in a single repository for further operating as one of a criterion in ranking page by a search engines. It is pretty easy idea. All we need is to go to the Mozilla and Google and ask them to communicate with each other.

I can’t patent this approach since I live in Russia but I don’t care – I just want to make Internet better.
