PageRank & User Data

SEO by the Sea writes that Yahoo Replaces PageRank Assumptions with User Data. I find the post interesting, mainly because I, like most of those who commented, was under the assumption that Google was already doing something like this already.

If Yahoo gets the patent (they've only just applied for it), this would mean that it is somehow different from what Google is using (or, very unlikely, that Google 'forgot' to patent it themselves). But in any case, the conversation at SEO by the Sea is quite interesting; if only to further prove that quantifying human behavior and constructing an equation to take in all the factors discussed is more math than I want to do.
