Re: Nofollow, Page Rank Sculpting
Personally, I never considered it page rank sculpting but have consistently used the nofollow attribute for pages that had value for visitors but wouldn't add any value to the index (terms of service, privacy policy, contact, paginated results, etc.)
With the revelation from Google that the page rank that would be assigned to those nofollowed links is just lost, instead of being transferred to the other links on the page, it doesn't make any sense to nofollow most of them anymore.
By sending the bots to the contact page, even though the page doesn't add any value to the index, it will keep the page rank in the system by spreading it from the internal links on that page.
Where it becomes a bit of a hassle is with forums, I'm going through mine and removing the links entirely from the profiles, printer friendly, etc. when they were simply nofollowed before. (Doesn't make any sense to have the indexing resources wasted on thousands of redundant pages)
