Facebook isn't helping you make new connections, Facebook doesn't develop new relationships, Facebook is just trying to be the most accurate model of your social graph. There's a part of me that feels somewhat bored by all of this.

I've never been much of a joiner.

Your biggest challenge as an entrepreneur is not concealing your idea from others or keeping your idea a secret, it is actually convincing people that you're not crazy and that you can pull this off.

You just keep pushing yourself harder and harder to achieve more and more - I don't think it's ever quite as glamorous as it appears on the outside.

Running a start-up is like eating glass. You just start to like the taste of your own blood.

In truth the social media elements of the Obama campaign, while extremely innovative, did not produce a lot of results.

It would be incredibly presumptuous and self-serving of me to believe that Facebook was the end of history. The only way it could possibly be the end of history is if it becomes some sort of artificial super intelligence that takes over the world.
