Zuckerberg: I'm still the man to run Facebook - Some think Facebook has grown beyond Mr Zuckerberg's control
Facebook has been a hot topic in the news lately, but Mark Zuckerberg has insisted he is still the best person to lead Facebook."When you're building something like Facebook which is unprecedented in the world," he said on Wednesday, "there are things that you're going to mess up.

"By design, he can’t be fired - he can only resign. Which is exactly what he should now do."
