Mobile is a lot closer to TV than it is to desktop.

I think video is a mega trend, almost as big as mobile.

If a product costs $10,000 or $20,000 it has limited use. This is what the first computers cost! Only when almost everyone is able to afford it will it be a real thing.

Facebook is inherently viral.

There have been misperceptions that we're trying to make all the information open on Facebook, and that's completely false. There are big buckets of information that we recommend that you share with only your friends privately. Then some of the more basic information, we recommend that that's visible to everyone.

Of course, hate speech and racism have no place on Facebook

The biggest risk is not taking any risk.
