Yahoo assumptions about PageRank and flaws

Some Yahoo assumptions about PageRank and flaws associated:

Internal and external links are often weighed equally even though internal links can be less reliable and more self-promotional. Some links, like disclaimer links, are rarely followed.
PageRank ignores that webpages are often purchased and repurposed, decay or become less valuable over time at variable rates.
Current calculations, like TrustRank, are engineered more to combat webspam than to reflect actual user behavior.
Sometimes PageRank deals with links in bulk, aggregating according host or domain, also known as blocked PageRank.

Last time I checked, even though Yahoo likes to bash Google, Google still produces better results. In the past the page rank may have been a simple calculation, but now I think their algorithm is much more complicated than that.

yahoo should try to refine their system first then talk about others.

I've taken a different approach with this one, having decided to tell a story without worrying about the beginning or the end. I'm not concerned with style or with structure, I just want to tell a story. I don't even care if its interesting, I just want to cover a certain sequence of events that I've invented.
