Re: PageRank algorithm
Pages were ranked that way until SEOs appeared on the scene gaming the system. Since then they've been layering hack upon hack to try to correct the SEO abuse and get the "pure" page rank.
Since the patent for page rank is expired, someone ought to introduce a 'pure' page rank search engine. It would probably be pretty good, since SEOs have long moved on from optimizing for the Google of the early 2000s, so long as it didn't get too popular and flew under the SEO radar.
