Ev was originally an angel investor in Odeo, then he decided to join and work on it after we'd been at it for about three months. When Apple crushed us with itunes podcasting integration, he and the rest of us were tinkering with ideas. Jack had a good one, and Ev was able to create the space for that idea to grow in to twitter. Is it luck that Ev invested in his neighbor, Noah Glass's startup Odeo? Is it luck that Jack decided to do twitter has his hackday project instead? His previous project was a universal js wrapper to play audio on the web sans flash.
What Ev is really good at is seeing, oh this seems interesting, let's tinker with it and help it grow. He places himself among interesting things and then supports them. He's right for not taking credit, he participated and helped, he was vital, but he wasn't the CREATOR.

Luck is way, way more important than most like to admit.
