Thank you Duane! I support your reasoning. I’d put it this way: pages were things customers would vote for - utile or not - with their clicks. A utility was first implied from pages, and then gauged by customers, with search engines providing the stage for this ‘poll’. Now we see a turn: utility is implied from engagement with a search engine itself, page is no longer pivotal, which makes the customers gauge not sources, but the whole answer.
