I don't worry. It's just not in my nature, really.

A huge amount of what goes on in the Middle East has to do with people being fed really bad information.

It just didn't occur to me, sitting at my computer, that I would end up travelling all over the world.

What can we put into the hands of people under oppressive regimes to help them? For me, a big part of it is information, knowledge - the ability to defeat propaganda by understanding it.

My original concept was to provide a free encyclopedia for every single person in the world.

My view is that good community management is like having good municipal government: You should be able to have dissenting opinions and so on, freedom of speech, but your grandmother should also be able to walk down the street at night without having to worry about getting mugged.

The goal is to give people a free encyclopedia to every person in the world, in their own language. Not just in a 'free beer' kind of way, but also in the free speech kind of way.
