"Digg is experimenting with achievements in Newsrooms. Currently, users are given the typical options of reading, Digging, or burying news stories. Users are rewarded for their actions via a points and rewards system. However some awards are dependent on his/her interaction with the community-- which adds an additional dynamic. For example, someone can’t keep submitting stories to get them promoted or onto the front page. Those rewards encourage users to not only invest time into the community but also to strive to submit quality content.
But more can be done to truly change the way people share and discover news on Digg and the answer to that may come with what comes next for games."
