Where I feel the most productive and engaged is when I'm buried in code, buried in some project, tweaking some designs. I'm certainly introverted.
Today there are millions of people making stuff and putting it into the world: that's become part of our identity and it shouldn't be limited to people who fancy themselves writers, or who are particularly witty or talented.
There are a lot of rich people in the world. There are very few people who have the privilege of getting to invent things that billions of people use.
Reading for me will be a combination of books, magazines, Tumblr and just kind of the Web in general on the iPad.
