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.

We thought that the Internet was going to connect us all together. As a young geek in rural Maine, I got excited about the Internet because it seemed that I could be connected to the world. What it's looking like increasingly is that the Web is connecting us back to ourselves.

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.

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.

In the last year, grassroots contributors like us gave more than $300 million to the Kerry campaign and the DNC, and proved that the Party doesn't need corporate cash to be competitive. Now it's our Party: we bought it, we own it, and we're going to take it back.

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.

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.
