Digg Now Using No Follow Selectively

One of the major advantages of Digg was the do follow attribute on links there. You submit your story, you get a back link

Just read on the digg blog that digg has decided to put the no follow attribute on some of the links on the site

These include

• Links in comment
• Submit that do not meet a certain threshold in popularity
• Links in user profiles

Obviously the question now is, what are they using as a measure of popularity?

• Is it the number of diggs a story gets
• Or the number of times the link is clicked on

Still a little unclear but I'll let you know if there is any further news
