The Web 2.0 world is defined by new ways of understanding ourselves, of creating value in our culture, of running companies, and of working together.

I think Facebook is an extraordinarily important part of the Internet ecosystem, and having a robust presence there is a critical part of any brand (or company's) strategy.

There will soon be streams of data coming from all manner of products - appliances, clothing, sporting goods, you name it. Wouldn't you rather live in a world where you can export the data from your son's football helmet to a new app that monitors force and impact against a cohort of high school players around the country?

The beauty of the innovation that flows from the open web is that no one has to ask for permission, get a credential, or win a Disrupt or Launch award to go prove their idea is worthy. They just... put up a page on the web, iterate, iterate, iterate... and eventually, a Facebook emerges.

In this digital age, there is no place to hide behind public relations people. This digital age requires leaders to be visible and authentic and to be able to communicate the decisions they've made and why they've made them, to be able to acknowledge when they've made a mistake and to move forward, to engage in the debate.

How can a parliamentarian or a leader in a country say, on the one hand, that we're going to support Greece but at the same time say that Greeks are lazy?

I will go to the next election saying to Australians, vote for me, vote for the Liberal Party, and I will become your PM. So I'm offering myself as the alternative PM - that's one way people describe the Leader of the Opposition - but I'm not in politics for myself to realize a personal ambition.
