The biggest challenge for open source is that as it enters the consumer market, as projects like WordPress and Firefox have done, you have to create a user experience that is on par or better than the proprietary alternatives.

One thing about open source is that even the failures contribute to the next thing that comes up. Unlike a company that could spend a million dollars in two years and fail and there's nothing really to show for it, if you spend a million dollars on open source, you probably have something amazing that other people can build on.

You can't build everything and there is no more a killer feature. Everyone has a different killer feature.

I am an optimist, and I believe that people are inherently good and that if you give everyone a voice and freedom of expression, the truth and the good will outweigh the bad. So, on the whole, I think the power that online distribution confers is a positive thing for society. Online we can act as a fifth estate.

Technology is closing the gap between what one can imagine and what one can do and as a result the equality of opportunity is unmatched in human history.

For me, it always comes back to the blogger, the author, the designer, the developer. You build software for that core individual person, and then smart organisations adopt it and dumb organisations die.

From the first time I held an iPhone, the space has evolved quickly, and people have shifted from reading content on their desktops to smartphones and iPads, even long-form stuff.
