According to Matt Cutts...
Google has phased out pagerank and is no longer using it and there will be no more updates of pagerank. Cutt's advice for webmasters and seo's is to create a massive amount of internal pages for your site (in the thousands to millions) and link farm them all together. That is how to get a site ranked high up now in google. Content means text and it only takes about a simple small paragraph of text on all the millions of internal pages to accomplish this. The text doesn't have to be relevant and can be about anything.
