Gosh, this is a weird situation...Are there some settings you can change from that maybe? Or is it because you're a digg member, and like mentioned above for you it opens with the 'Digg userbar' when clicking it?
Instead of me, as an unlogged in member, it goes to the site directly?
Most social bookmarking sites go to nofollow sooner or later. That way they control how much pagerank they hand off to other sites.
If digg is not dofollow right now, they will be at some point in time.
What I notice is that when
I'm LOGGED IN I see on the browser bar the short links (e.g. digg.com/d3zam1) and when
I LOGGED OUT, I see the regular links (e.g. fansided.com/2009/03/70/200/news-and-spotlight.html)
Even digg use do follow, i think the link is not quality link since your digg page is become subpage. And subpage have no PR, only digg mainpage is have PR.
But it's still usefull
Links in comments were nofollow last time I checked. As well as news titles' links.
But that was about a month ago.
