I blacklist websites that I feel are bad for me using /etc/hosts, but I still consume too much news. I was thinking about this today and how to alleviate it without hiding my head in the sand. Honestly a weekly news magazine like The Economist would probably be enough.
Ideally I'd have a tool that lets me react once to a given news item and then track it over time, filtering out repetitive or meta news (especially news about other people's reactions to the news), show me only substantive changes over time, and ideally with a weight that (geometrically) increases with proximity. What is humbling is to realize how easily led we are, how things that seem so important, so vital, end up just...forgotten when the news dies down. It's actually quite scary when you think about it, almost as if your reactions to things aren't quite your own! This tool would help recover that control.
