I don't think people buy records because of anything that happens on Facebook. They buy records cause they're friends say 'I bought this record and I love it.'
I can't do Twitter or Facebook, mostly because I feel like I'm the type of person who has to regiment the amount of time I spend doing certain things or I'll just wade in it, and then I'll never come out.
Sometimes I'll write a tweet that I'll just be like, 'Why do I have to say this to all of these people?' It's like writing a Facebook status: it's the same. I view tweeting as like writing a Facebook status. Remember when we used to write statuses?
I was on Facebook. I was on MySpace. And somebody said to me, You should check out this thing called Twitter. I knew five people that were on it, so I started following those people and seeing what they were doing, and then I applied my own sensibility to it. The more that I shared, the more people started following me.
If Facebook gets your entire social graph, you don't necessarily want to share everything with your entire social graph. You might wanna parse that social graph. So there's a company called PASS that is a private social network that I personally use for my friends and my family.
I think at all social networks, be it Facebook or Twitter or whatever it is, there's an ecosystem that exist there. But there's also an ego system that exists there.
You can't invent Google, Facebook or the iPod unless you've mastered the basics, are willing to put in long hours and can pick yourself up from the floor when life knocks you down the first 10 times.
