It's important to credit the brave people that take chances to stand up to regimes. They're the star.

Even the simplest tools can empower people to do great things.

I think Twitter has brought something totally new to the table.

I started designing book jackets, which was great because I was good at it. And then from there I decided to become a freelance graphic designer and I needed to expand beyond book jackets, so I taught myself web design, and then in 1999 some friends of mine decided to start a company called Xanga.com, which was a very early kind of social network slash blogging community.

I never even graduated college. I never finished learning, as it were, and I have a psychological need to be in a learning environment at all times.

I think before Twitter people didn't think that way, not in any sort of meaningful or specific way, so what I'm trying to say, if we're trying a bunch of stuff, a lot of cool and great social stuff, a lot of platform stuff, then some of it will stick, and some of it will be junked over. Some of it will be just like the cell phone, you can't imagine not having it.

If people are passionate about your product, whether it's because they're hating or loving it, those are both good scenarios.
