I dunno if I am getting a step beyond from giving specific answer to the question. But one thing I have learned is that social bookmarking links may not have a good link value / juice when relevance is concerned. For example if you have a link from an article, the entire page would have your keywords sprinkled here and there. This could add to link juice.
But as far as social bookmarks are concerned, links may have a very good value.
