digg stops shouting
Since today digg doesn't allow shouting anymore. What was a "shout" ? If you submitted an article or you find a good article at digg you could share this article with your friends. For sharing the article you sent a "shout" to them. If you wanted to communicate with one of your friends you could sent him a "shout" (message).
