And why we should not uses nofollow? I mean who the heck want to make their login page has PR 7? By having several nofollow link, from our homepage to some of our unimportant internal page, at least we keep the link juice to homepage.
(Illustration: homepage with 10 link juice links to 10 pages, 5 nofollowed, thus only passing 5 link juice to 5 followed page, thus keeping 5 link juice to the page itself, thus it ranks higher.)
