Mark Zuckerberg is becoming a CEO before our very eyes. Zuckerberg, CEO of Facebook has been a participant at our Web 2.0 Summit Conference for the last several years. This year however, in a discussion on stage with John Battelle and Tim O'Reilly, we saw Zuckerberg 2.0. A more mature, confident and articulate leader. Yes as some have observed he has obviously received significant media training. And yes, at times he was a bit mechanical in his answers and mannerisms. Frankly if the CEO of a company the size and scope of Facebook wasn't getting media training I'd be concerned. I well remember listening to Bill Gates, Michael Dell and Steve Jobs at similar stages of their development and all of them had to learn how to communicate, present and deal with the media. And none of them were "naturals" at one to many communication either. That generation of technology executive also wasn't dealing with the range of media that exists today. So take a look at the interview and watch a technology executive maturing into the role of a CEO.
