I do my best stuff midmorning and superlate at night, from 1 to 5 in the morning. Some people don't need sleep. I actually do need sleep. I just sleep all the time. I'll catch naps in the afternoon, or I'll take a 20-minute snooze in the office - just all the time. Our business is 24 hours. Our guys in Europe come online at midnight.

Twitter is the ultimate service for the mobile age. Its simplification and constraint of the publishing medium to 140 characters is perfectly complementary to a mobile experience. People still need longer stuff, but they see the headline on Twitter or Facebook.

If you make the Internet, live on the internet.

I like to read first thing in the morning. I'm addicted to the Kindle. I read a lot of business books, because I feel like I should figure out how to be a real businessman before someone figures out that I'm not one. I really enjoy reading classics as well, which I try to work in once every two months.

Simplicity not simplistic.

One of the things I've been working on for the past few months is a radical simplification of the interface.

For me, it always comes back to the blogger, the author, the designer, the developer. You build software for that core individual person, and then smart organisations adopt it and dumb organisations die.
