Remember "Trust Rank" could be nothing more than a human goggle editor, (
Remember Google Eval last year?) adding this trust weight to major websites.
As we saw in some
very generic keywords on Google the relevance is very exceptional. Why? I don't know, lets guess. One reason comes to mind that these websites have been given this "Trust Rank" factor SPECIFICALLY for that keyword queried. Remember one theory is when this Trust Rank is added to a website keyword is actually associated with it.
Interesting Slashdot on Trust Rrank as it applies to Google News.

Now for
PR, who cares, to me it is a little green bar.
