“Building and moving quickly for five years hasn’t been easy, and we aren’t finished. As we celebrate Facebook’s 5th birthday, we continue to work hard to evolve Facebook and make it as simple as possible to communicate with and understand the people and entities that matter to you,” wrote Mr Zuckerberg.
