sorry i dont agree at all tedster. The evidence is that ever scrolling pages serve the user better requiring less clicks to get further into the content of the page. if the user got to that part of the page which with google is below the fold then the intention to look further than 7 results is already there. Its pretty clear whats going on, it goes hand in hand with host crowding.
I know we wont see ever scrolling on the serps pages with google any time soon, 1 because of the clear current direction and 2 because of the added google goodies that change on page click.
