Facebook is changing its news feed algorithms, but will it make engagement on the site more 'meaningful'? We hear how businesses and publishers will be affected from Lisa-Maria Neudert,a researcher at the Oxford Internet Institute. Plus, can we trust that the latest tweaks to the algorithms will be in the best interests of Facebook users? We get analysis from Max Stossel of the 'Time Well Spent' initiative in New York. Plus, a trial of slightly different changes to Facebook's news feed has been in place since October 2017 in six countries worldwide, including Sri Lanka. We hear more from Chevaan Daniel, group director of the Capital Maharaja Organisation, which owns Sri Lanka's largest news network, NewsFirst. (Picture: Social like icon, Credit: Getty Images)
