Mine have all stayed the same, apart from one site which went from PR4, to PR2 (a site I don't really use, but all my sites link to it.) Strange, as the homepage which I have all the sites linking to is PR2, yet the internal pages which only have links from the page of that site, have PR3.
OK, now I hope someone could give me a simple answer as to why my website didn't receive a higher pagerank from the current of 0. I have at least one reputable site with pagerank 5 linking back, another pr4 site linking from several pr4 subpages, and about 40k backlinks in yahoo, 5,5k after the Google BL update. What are the chances of all the rest of the domains to be pr0 and not letting the higher pagerank sites pass some pr? PS. I have a 1 backlink at a pr6 site's mainpage too.
Unlike the last PR update, some of my strong sites have increased, and weak sites have dropped off. Something im happy with when compared to googles inaccurate last PR update.
