Facebook Inc Chief Executive Mark Zuckerberg said his goal for 2018 was to put the business he co-founded on a more solid footing, a break with his longstanding practice of setting a purely personal annual goal.

"The world feels anxious and divided, and Facebook has a lot of work to do," Zuckerberg, at 33 one of the world's wealthiest people, wrote in a post on the No. 1 social media network. In past years, his New Year's resolutions have included learning Mandarin, reading two books a month and traveling to U.S. states he had not yet visited. This year, his post described Facebook as standing at a crossroads that required his attention. He cited the spread of hate speech on social media, use of Facebook by Russia and other countries to disseminate propaganda and criticism that the platform can be an addictive waste of time. A new law in Germany requires social networks such as Facebook and Twitter Inc to remove online hate speech or face fines. In the United States, lawmakers have criticized Facebook for failing to prevent Russian operatives from using its platform to meddle in the 2016 U.S. elections. In addition, ex-Facebook executives have publicly questioned whether using the network leads to unhealthy behaviors.

Zuckerberg said his "personal challenge for 2018 is to focus on fixing these important issues." He added that the pledge "may not seem like a personal challenge on its face," but that he would learn a lot. He did not say what he would do.
