Hooray! Pre-Google search sucked. It was really bad.

I don't know what this means. Humans have never audited/controlled what gets indexed by crawlers. It's always automata unleashed on the data. It would be terribly unproductive to prune or tune the index with humans. However, using humans as a part of a feedback loop to tune an algorithm is a good idea [presumably all search engines do something like this].
