So true, the difference was monumental. Pagerank was a huge breakthrough that seems so simple and so obvious in hindsight, it's clear why it changed everything. The popularity of a website shouldn't be based on the number of times they can stuff keywords into a page, it should be based on the number of human beings who used the site and determined it was valuable enough to link to. I don't know if pagerank is used anymore, but at the time, with the state of the web then, it was an incredible breakthrough.
