on reddit/digg, people submit the actual news link that generated the comments based on that news
my idea is, people submit the comment first on any specific topic that result people produced a 'news' based on that comments

Maybe "article" is a better term, or even "essay".
Someone chooses a topic, people discuss it, and then someone works that discussion into an essay about that topic.
