Mr Zuckerberg said he intended to focus on “important issues”, which he listed as “protecting our community from abuse and hate, defending against interference by nation states, or making sure that time spent on Facebook is time well spent”.
“We won’t prevent all mistakes or abuse, but we currently make too many errors enforcing our policies and preventing misuse of our tools,” he wrote.
“If we’re successful this year then we’ll end 2018 on a much better trajectory.”
The Facebook CEO said he would learn more by looking intensely at those issues than by doing something completely separate. In the past his New Year resolutions have included wearing a tie every day and killing his own food.
But critics questioned why he needed to make a yearly challenge of these issues.
“Zuckerberg’s 2018 personal challenge for himself is…doing the work he should be doing as Facebook CEO anyway,” tweeted tech writer Maya Kossoff.
