I know se's only take into account the pr of the page your link is on, not the homepage pr. Just wondering, if you have a link on two pr0 pages and one of the homepages has a pr3 and the other homepage has a pr8, does one link weigh more than the other or are they viewed the same? Did I confuse anyone?
Probably...since the one that is on a PR8 site will likely get a higher PR than the other one on the next PR update.
