I thought this thread from GPWA / Elgoog was worth having over here, too in case anyone missed it. I just finished adding a lot more call's to action on my pages, and then this comes out 
(full thread: Google Changes Treatment of PR 'Saved' by rel=nofollow Sculpting - Gambling Portal Webmasters Association)

NoFollow To Cause Revolt: Wasted PageRank via Sculpting & JavaScript Links Require NoFollow
Google Changes Treatment of PR 'Saved' by rel=nofollow Sculpting
The rel="nofollow" attribute still blocks <acronym title="Page Ranking">PR</acronym> transfer through that particular link. But it no longer creates an increase in the <acronym title="Page Ranking">PR</acronym> that is transferred by other links on the page. The blocked <acronym title="Page Ranking">PR</acronym> now just falls into a black hole.
------------------
The rel="nofollow" attribute... implemented jointly by the major engines... was initially intended to block PageRank credit from blog comments. Its use was expanded by Google to blog transmission of <acronym title="Page Ranking">PR</acronym> credit from paid links.
Questions arose about whether it might be used to "sculpt" PageRank flow within a site. With PageRank sculpting, you could block <acronym title="Page Ranking">PR</acronym> transmission to unimportant pages, and channel the rest to pages you deemed important.
Prior to rel="nofollow", if you had 10 outbound links from a page, each of those links transmitted 10% of your outgoing PageRank. There was considerable discussion here on WebmasterWorld, among other places, about whether "nofollowing" some of those links would increase the amount of <acronym title="Page Ranking">PR</acronym> sent to the remaining pages....
The consensus ultimately was yes... if you nofollowed half of those 10 links, eg, the remaining 5 would now each transmit 20% of the <acronym title="Page Ranking">PR</acronym> credit available from the page... and you'd be giving extra credit to those pages that weren't nofollowed. This consensus was confirmed publicly by Google.
The announced change now means that the pages that aren't nofollowed will no longer get the extra linking credit. That credit will now be divided evenly among all links, but nofollowed links will still be blocked from crawling.
