I meet with Satya [Nadella] what probably amounts to four or five times a year - either to brainstorm something or just as a shareholder, we'll sit down and chat. That's always quite helpful for me and hopefully him in terms of thinking things through. I still have a number of friends and colleagues who occasionally want to brainstorm or chat about something, and that's always fun.

Almost three years ago, when I retired, my wife and I were talking about our philanthropic work and how does one help give opportunity, particularly to kids growing up in very disadvantaged situations.And my initial kind of sense was, the government does that primarily, and what we should mostly do is pay our taxes. My wife said, no, I don't think that's quite right for us. We need to do more. We can do better.

There's a lot of Google fascination out there and we share it, and we're going to compete, we're going to compete very, very hard.

I've got my kids brainwashed: You don't use Google, and you don't use an iPod.

I've been doing lot of work, and hopefully will bring it to fruition in a way people can see it, really understanding - this is going to sound funny, but what does government really do, how is it really funded, and what measures exist to evaluate how it does at what it does? No forecast, no policy, no prediction, just a realistic perspective on what is. Call it like a "10k for government" we've been working on with a website, with additional data.

I think there are lots of opportunities to improve the product. When you read the press, people say, "Oh, the product needs improvement." I look at that and say, "Hey, that's an exciting thing to get behind!" Because they can improve that product. That leaves more upside from an innovation and revenue potential than you're gonna find in a lot of places. So you could say that's a downside, I see that as an opportunity.

Accessible design is good design - it benefits people who don't have disabilities as well as people who do. Accessibility is all about removing barriers and providing the benefits of technology for everyone.
