They're simply weighted differently. Forget page rank and keywords etc.....the main thing driving Google these days is Trust Rank. In their never-ending quest to fight spam, it's not just how many links, it's the AGE of the links and Trust Rank of the sites they come from. As just one example, an old dmoz link from 1998 is still treated like gold from Google while Yahoo and MSN could care less.
