Digg made redesign. In result most of the people, long year users of Digg are angry. They don't like the new design, they don't like the problems. In fact, if you try to visit the Digg system and try to share link, you will see, that Digg can't submit the article. Or other page with error...

So the people are not happy with the new digg. And they submit stories from Reddit. This is something to remember. Digg didn't made good beta testing of their service. Digg tolerated many users to use their system as free advertising platform. Me and many other didn't had this chance. Every story submitted to Digg is lost in the mess of stories.
So the people close their accounts. The don't want to use Digg anymore. They are disappointed. I am one of the disappointed users, but I will stay for while to see what will happen next.
When I try to submit article, Digg tells me that the link is incorrect. So I can't use Digg now. I hope that they will fix their system and will be better. Because I will stop using digg, if they don't hear the voice of their users.
