...but in essence, I don't see how anything has really changed from a pragmatic stance. The answer seems to be:
1. Produce more pages reflecting what users are looking for (phrases) with content that is good enough to keep them on the page and site.
2. Get more links, the best being those that are given based on quality of content since those typically a lower degree of manipulation.
3. Drive user behavior of your site (get them to the site, keep them on the site) and use this plus site reputation to gain trust.
Wikipedia manages to keep users on the site for quite a while. I can't tell you how many times a visit has turned into seven different bounce-arounds just by following the various in-text internal links.
