Knowledge of how things fail, as much as how they are started. He's not just an ideas person, he's also a signing-the-checks person and a making-the-deals person and a catching-the-flak person. In short, a business guy.

I have never liked or used Digg so I'm not carrying any water for him. But I've had that 'I do all the work and he gets all the credit' feeling, only to realize that the difference was that I had taken a job rather than starting a business. Code is just a means to an end. Sure, architecture and good code are important, but they're important so that users don't have to care what's making it work. When I walk into a store, my life is in the hands of the architects and laborers who built the structure; and having worked in construction, I can tell you that they did a hell of a lot of hard work. However, that's incidental to my purpose in entering the store, and I don't hold it against the store owner that he didn't personally build any of the structure his business operates in.
