Facebook boss Mark Zuckerberg has set his "personal challenge" for 2018: to fix Facebook.
Each year Mr Zuckerberg sets himself a goal to achieve by the end of the year.
In past years, these goals have included learning Mandarin, visiting every US state and reading 25 books.
But in 2018, Mr Zuckerberg has vowed to fix Facebook's problems.
The tech giant came under fire when it was revealed that Russia used Facebook to interfere in the 2016 US presidential election through targeted advertising.
- Facebook to alert users influenced by fake Russian accounts
- UK presses Facebook on Russia-linked ads
In a post shared on Friday (NZ time), Mr Zuckerberg admitted the company makes "too many errors enforcing policies and preventing misuse".
"The world feels anxious and divided, and Facebook has a lot of work to do - whether it's 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.
"This will be a serious year of self-improvement and I'm looking forward to learning from working to fix our issues together."
