Digg’s fundamental principle is social-generated content, the new media where the users are the reporters and that only stories that the users aka “Digg-nation” finds interesting. But this principle is in jeopardy as the blogosphere has buzzed many times about “Digg-Gangs” and how certain users who digg something carry more weight then other digg users which allows stories to get to more prominent positions such as the home page and category home pages.
Now I can understand why this is in place. To help prevent spammers and such from getting their stories in a prominent position but the negative effect of this is you are isolating new users who are submitting quality content.
