i like the idea of customized social news gathering, but i'm not sure if a community structure is the right way to do it. i don't think most people want to limit themselves to a particular community of stories. most of us have pretty broad interests and, while we may want to read more about a particular field over other fields, that doesn't necessarily mean we want to read ONLY about that field.

i envision a system where you sign up for an account and you subscribe to your own personal RSS feed with content similar to Digg/Reddit and over time the site learns your interests based on the stories that you click on from your RSS reader. each feed would have user-generated tags associated with it and will begin showing more (but perhaps less popular) feeds that share tags with feeds that you've previously viewed. over time, your personalized RSS would contain only feeds that it knows you're interested in, and the random feeds it included at the beginning in order to learn your interests would gradually be phased out.

the layout of the site is great though. i'm just not into the community/forum idea too much.
