I would love to see something like this:

  (Steve Jobs Died) (14 articles, newest on 11th of fyftember)

Articles on the same event within short timespan would be compressed into a single line you can expand by clicking.

One implementation could be some kind of special purpose tagging functionality, similar to flagging, but with a keyword argument. Maybe the tag should even have a limited lifespan - until you can no longer assign it. Submissions under the same tag would be compressed into an expandable list, similar to threaded comments. Please make the chat flood stop!
