The days of you having a different image for your work friends or co-workers and for the other people you know are probably coming to an end pretty quickly. Having two identities for yourself is an example of a lack of integrity.

By giving people the power to share, we're making the world more transparent.

I'm trying to make the world a more open place by helping people connect and share.

When you want to change things, you can't please everyone. If you do please everyone, you aren't making enough progress.

The point of Facebook isn't the features, it's the people.

We want Facebook to be one of the best places people can go to learn how to build stuff. If you want to build a company, nothing better than jumping in and trying to build one. But Facebook is also great for entrepreneurs/hackers. If people want to come for a few years and move on and build something great, that's something we're proud of.

Books allow you to fully explore a topic and immerse yourself in a deeper way than most media today. I'm looking forward to shifting more of my media diet towards reading books.
