lol! Like you, we rss hoggers don't sleep either :p I think most posts on here are a result of users aggregating through rss feeds to post whatever's hot on the web.

Bury should work fine (perhaps it should only be accessible by top users to avoid abuse). Another possible solution is to survey the user's past behavior to create a collaborative filter. The filtered news could then be displayed in a "Recommended" tab. As yc.news grows to a certain critical level, this might just become a necessity.
