I do not yet have a definitive answer question on that so far, but the data I do have seems to say that href="#" links do increase the divisor, lowering the value of any other link on the page. In other words, it gets evaluated like a nofollow link.
If I understood well what you are saying, then bookmarking from within the page lowers PR your page passes to other pages? I can understand why it would be wise to be ignored in PR & anchor passing when linking to anchor within own page, but it seems unfair if it is just PR black hole.
Meaning that because of SEO effect one should not use bookmarks within own page even though it would make a sense to a visitor, especially in cases where the bodycopy is longer. So as a result you are inclined to break such page into two (or more) as that way PR would still be passed and circulated.
