I agree with you. It'd take a huge company with tons of resources at its disposal to do something like this if it's possible at all. But if anyone could hire and train the army necessary to do it, it'd be google or facebook. (Apple already does it. Apple News is edited by real apple-employed humans but its far smaller in scope).

I think real solutions are gonna require us to break out of our tech-focused approaches and find ways to get Google, Facebook, Twitter to really start to care about fixing this stuff. Unfortunately I think that means it'll have to start costing them.
