Social Bookmarking Sites Which Don’t Use NoFollow : Bookmarks and Search Engines

Social bookmarking allows web users to search, share, organize, and store the bookmarks of different web pages. This can be done publicly or privately (in private groups), or a combination of the two. People who are allowed to view the bookmarks can view them using a variety of different functions to sort and tag them....

.....NoFollow is a non-standard HTML attribute value which is used to police the outbound link value of user generated content, especially blog commenting. NoFollow is used to communicate with search engines to tell them that a link should not be used to pass on link juice, or “PageRank”.
