But if you ignore user behaviour on a page you have a huge hole which you can only guess about from data obtained from behaviour within the search results. That's a big open door to webspam.
To me, guessing about user behaviour on a page is worse than making assumptions based on a representative sample of actual user behaviour metrics.
The wave idea may well be the way they are headed in terms of personalisation but I just cant see any way it can exclude on page metrics.
