Digg isnt adding nofollow to everything, just the links that theyre less sure about.

Once a story looks real to them, I can imagine that they would lift the nofollow.Cutts also shared a couple of videos he has done where he discusses how Google takes a similar approach, and answers two questions about Nofollow You may recall the topic of the first video from an article WebProNews ran about it this week. Cutts specifically talks about Google Knol, and how at first authors receive nofollowed links, but as the authors gain more turst, they sometimes remove the nofollows. So the new move by Digg is a positive change in my opinion, because Digg decreases the benefit for spammy stories but Digg still helps normal and highquality stories in the search engines, says Cutts.Digg said the decision was made after consultation with leading experts in the SEOSEM and link spam fields. The company says it is looking out for content providers and the Digg community.
