We've seen how grassroots journalism by blogs has had an impact at various points politically, as ordinary people have amplified stories that were being ignored by the traditional press.

I'm a big advocate of freedom: freedom of speech, freedom of expression, freedom of thought.

I worry about censorship in many parts of the world.

I still believe there is a need to open up search and it will come eventually. It is very important to challenge the current models.

There's a big tendency to gravitate toward a closed and proprietary approach too easily.

I think that reality exists and that it's knowable.

The real struggle is not between the right and the left but between the party of the thoughtful and the party of the jerks.
