From an interview by Internet Evolution:

Internet Evolution: You’ve had a front-row seat for the commercialization, regulation, and funding of the Internet. What’s been the biggest surprise for you about how the Internet has evolved? And what’s been your biggest disappointment?

Esther Dyson: Well, surprise and disappointment are the same… There are two big things: First, I was a much bigger fan of anonymity then than I am now. I thought it was cool. And it is, but it turns out anonymity really encourages bad behavior. I’m not in favor of the government tracking everybody and so forth, [but] at least persistent pseudonyms and communities and stuff like that makes everything a nicer place.

It’s like a lot of things. I’m pro choice, but I think abortion is an unfortunate thing. I think the same thing about anonymity: Everybody should have the right to it, but it’s not something one wants to encourage. And that’s not weasel words, that’s the reality of it.

[Anonymity] should be allowed. People should be able to make that choice, and there are many reasons to make that choice. If you live in an oppressive regime, you may well want people to be able to remain anonymous or have secret communications. But at the same time, it should not be encouraged, and it should be acknowledged that it’s a response to a bad situation.
