People are surprised to find out that an awful lot of people think that they're idiots.

I think it's pretty clear that the internet as a whole has not had a strong notion of identity. And identity means, 'Who am I?' Fundamentally, what Facebook has done has built a way to figure out who people are...

Technology is always evolving, and companies.. not just search companies.. can't be afraid to take advantage of change.

Mobile use is growing faster than all of Google's internal predictions.

Within search results, information tied to verified online profiles will be ranked higher than content without such verification, which will result in most users naturally clicking on the top (verified) results. The true cost of remaining anonymous, then, might be irrelevance.

Around 400 million people in the last year got a smartphone. If you think that’s a big deal, imagine the impact on that person in the developing world.

The best thing that would happen is for Facebook to open up its data. Failing that, there are other ways to get that information.
