I work for a medium sized public company (500 people), that went public about 5 years ago. After going public we had a CEO that was decent, but didn't know how to run a company to make it profitable. After 1.5 years of missing earnings we got a new CEO and our stock is 10x the value it was back then.
If Zuckerburg is still playing a part in engineering, he should be the CTO of the company, not the CEO. Having a business minded person person holding the reigns of a company can help the shareholders, otherwise the stock price will have a good chance to continue its descent.
Facebook is in a quandary because it would be difficult to monetize (to the extent that it reclaims the 100B market cap) and still retain its user base. And if these business people existed, don't you think Facebook would have already hired them?
