I've just noticed one our heavy traffic sites in terms of page views take a big jump in both PR and rankings - the on page SEO is pretty bad with this site in general so I was taking a guess user activity might just be a factor. This particular site is much more about users than any SEO so in this case Google is getting it right.
So there are 2 things here -
Users pattern determine a % of PR
Users pattern determine a % of search weight
It makes sense that sites that are sticky and/or refer to other sites via clicked links would be more valuable...and should be placed higher in the SERPs than a site that gets hit and is left via the back button immediately.
