We need to be talking about the political implications of what we've built, and figuring out how to fix our mess. This is like the period before the hurricane: everyone should be busy boarding up windows, and you can't do that if you decide you're just not going to talk about the coming storm because it makes you feel bad.
I think we should aim for reasonable ratios. Maybe we should have an algorithm that categorized stories and tried to create a certain ratio of tech:politics:curiosities:startups, for example?
