London | Mark Zuckerberg‘s personal wealth has fallen by nearly $US7 billion ($9.6 billion) in a few hours, knocking him down a notch on the list of the world’s richest people, after a whistleblower came forward and outages took Facebook’s flagship products offline.
A selloff sent the social-media giant’s stock plummeting about 5 per cent on Monday US time, adding to a drop of about 15 per cent since mid-September.
