Rather than saying people aren't interested when things don't take off, you should take it on yourself to say, 'I'm not doing a great job of telling the story in a way that makes it interesting.

The algorithms that orchestrate our ads are starting to orchestrate our lives.

More voices means less trust in any given voice.

If you Google some sites about the link between vaccines and autism, you can very quickly find that Google is repeating back to you your view about whether that link exists and not what scientists know, which is that there isn't a link between vaccines and autism. It's a feedback loop that's invisible.

By constantly moving the flashlight of your attention to the perimeter of your understanding, you enlarge your sense of the world.

We really need the Internet to be that thing that we all dreamed of it being. We need it to connect us all together. We need it to introduce us to new ideas and new people and different perspectives. And it's not going to do that if it leaves us all isolated in a Web of one.

I think it's easier than ever to hear only what you want to hear. That doesn't make a good citizen.

It's a civic virtue to be exposed to things that appear to be outside your interest. In a complex world, almost everything affects you – that closes the loop on pecuniary self-interest. Customers are always right, but people aren't.

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.

Facebook was looking at which links I clicked on, and it was noticing that I was clicking more on my liberal friends' links than on my conservative friends' links. And without consulting me about it, it had edited them out. They disappeared.

In a personalized world, important but complex or unpleasant issues are less likely to come to our attention at all.

Personalization is based on a bargain. In exchange for the service of filtering, you hand large companies an enormous amount of data about your daily life--much of whic you might not trust your friends with.

In a broadcast society, there were these gatekeepers, the editors, and they controlled the flows of information. Along came the Internet and it swept them out of the way, and it allowed all of us to connect together, and it was awesome. But that's not actually what's happening right now.

A world constructed from the familiar is the world in which there's nothing to learn.

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.

Whether it's Facebook or Google or the other companies, that basic principle that users should be able to see and control information about them that they themselves have revealed to the companies is not baked into how the companies work. But it's bigger than privacy. Privacy is about what you're willing to reveal about yourself.
