I'm not a fan of giving a website a simple number like an IQ rating because like people they can vary in all kinds of different ways. So I'd be interested in different organisations labelling websites in different ways.

I have built a moat around myself, along with ways over that moat so that people can ask questions.

I'm very aware there are lots of other people who are just bright and working just as hard, with just the same dedication to make the world a good place.

I think IT projects are about supporting social systems - about communications between people and machines. They tend to fail due to cultural issues.

We can't blame the technology when we make mistakes.

What I do has to be a function of what I can do, not a function of what people ask me to do.

One way to think about the magnitude of the changes to come is to think about how you went about your business before powerful Web search engines. You probably wouldn't have imagined that a world of answers would be available to you in under a second. The next set of advances will have an different effect, but similar in magnitude.
