I updated my grilling app, iGrill, today and it now has Facebook integration that lets you see what other people are grilling right now around the world. Awesome.

It occurred to me that building a company was the best way to align a group of people towards building something great. And its really... it's a good organizational structure where you can really reward people. If they're building something that's good, you can you work with partners and reward them if the product that you're developing work well. It's a good way to get the best people involved to build something very good.

You could probably go all the way back to the first books. I bet people said 'why should you read when you could talk to other people?' The point of reading is that you get to deeply immerse yourself in a person's perspective. Right? Same thing with newspapers or phones or TVs. Soon it will be VR, I bet.

The question isn't, 'What do we want to know about people?', It's, 'What do people want to tell about themselves?'

Facebook is uniquely positioned to answer questions that people have, like, what sushi restaurants have my friends gone to in New York lately and liked? These are queries you could potentially do with Facebook that you couldn't do with anything else, we just have to do it.

Our goal is not to build a platform; it's to be cross all of them.

The unsupervised learning is the way most people will learn in the future. You have this model of how the world works in your head and you're refining it to predict what you think is going to happen in the future.
