I would agree that the free exchange of ideas is the great promise of the internet, but I disagree that Facebook or any high traffic website has any responsibility to blindly post what is popular.

That kind of thing is relegated to smaller and active communities that can decide for themselves what content to exchange.

A highly trafficked global community has to be managed differently, and a system that is completely democratic will be gamed because of the eyeballs it has in front of it.

Facebook, Digg, Reddit, Slashdot, etc. are all sites that have been heavily targeted by astroturfing campaigns. They've all attacked that problem in their own ways, and they all have failed spectacularly.

One way of attacking the problem is curating popular content. It works but it doesn't. Show me the website that has more than a few million daily visitors that has democratized information, and I'll show you a website that is being gamed by marketers. (Seriously... because if it isn't already, I'd love to make a quick buck)
