People Skills - The Character Traits of an Entrepreneur

In a previous post and many similar posts, the community has talked about the characteristics of an entrepreneur. What about people skills? Let's be honest - hackers aren't known for having great people skills either.

This also reminds me of a chapter in Founders at Work. One interview highlighted changing the culture of hackers to be more professional, but this interviewee gave up that idea.

Thoughts? Anecdotes? How do hackers and co-founders develop people skills?
