"If you only have one shot at writing a headline, there's a lot of pressure." — Eli Pariser

Democracy actually requires that the whole public be able to see common problems and address them and step outside of their own sort of narrow self-interest to do so.

It feels great to have your own views reflected back to you, and you feel so right, but actually it's very dangerous. Because to make good decisions, you need to have a clear view of what all the options are.

I think that people post to social media to help shape their public identity.

There's the idea that people should be able to control how the information that they're giving to websites is used and monetized in a more clear and powerful way. That's something that probably will need government action.
