That is where it gets hard, but I think its doable. And just to play with the thought experiment you would probably weigh things. Like would you want to see any car accidents on your street within 50 feet of your house? Maybe yes. 2 miles away? Probably not, but may be if they have a fatality sure. Car accident of a friend in another country? Maybe. A train wreck with 100 deaths in your state? Basically you can adjust the likelihood of something showing on your feed by severity weighted by location and friend graph (showing less severe things closer to you and more severe things further away). This matches how I think humans actually process information.
