Mark Zuckerberg sets toughest new year's goal yet: fixing Facebook

CEO reveals this year's 'personal challenge' as site faces relentless criticism over spreading of misinformation and damage to users' mental health

Amid unceasing criticism of Facebook's immense power and pernicious impact on society, its CEO, Mark Zuckerberg, announced Thursday that his "personal challenge" for 2018 will be "to focus on fixing these important issues".

Zuckerberg's new year's resolution - a tradition for the executive who in previous years has pledged to learn Mandarin, run 365 miles, and read a book each week - is a remarkable acknowledgment of the terrible year Facebook has had.
