Mr Zuckerberg has famously set himself
challenges every year since 2009.
Facebook launched in 2004.
Social media firms have come under fire
for allowing so-called fake news ahead of
US and other elections to spread.
Facebook in particular has been criticised
for allowing Russia-linked political
ads in the run-up to the 2016 US
presidential vote .
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.
He said one of the issues he intended to
tackle was the debate about
centralisation and decentralisation.
Technology had the promise of putting
more power into people’s hands but
many people had now lost faith in that
promise and thought technology actually
centralised power, he said.
Mr Zuckerberg added that encryption
and digital currency had the power to
counter this trend, and said he would
explore how to use them at Facebook.
“This will be a serious year of self-
improvement and I’m looking forward to
learning from working to fix our issues
together,” he concluded.
