I don't disagree that there are too many bin Laden stories, but I'd be hesitant to make any algorithmic changes based on a story that is a once-a-year magnitude event.
The problem isn't that there are too many bin Laden stories: it's that there are any. I know how to get to CNN or the NYT and it's completely pointless to post bin Laden stories here period. I would also say that politics and religion, even if there'a some vague technology connection, should be verboten. There should be some minimum level of genuinely applied or theoretical computing or math content.
