Ever since Napster I've dreamt of building a product similar to Spotify.

There is no simple answer to what I think.

I think Facebook's biggest problem is the glut of information that Facebook's power users are overwhelmed with.

My interactions with Sorkin were agonisingly weird. He is by far the weirdest person I have ever met. I had dinner with him and a few hours before I got an e-mail from his assistant saying, 'Sean, this does not need to be a long conversation. Aaron is only going to use it to win your trust.'

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.

Facebook is such a basic utility. It's something that is such a part of peoples' lives, I think it's hard to imagine it going away.

You actually don't want people thinking your product is cool, because then you're a fad.
