Facebook News Feed Changes’ Impact on Democracy

Facebook News Feed Changes’ Impact on Democracy

Facebook News Feed Changes’ Impact on Democracy.
Facebook is testing a major change that would shift non-promoted posts out of its news feed, a move that could be catastrophic for publishers relying on the social network for their audience. A new system being trialled in six countries including Slovakia, Serbia and Sri Lanka sees almost all non-promoted posts shifted over to a secondary feed, leaving the main feed focused entirely on original content from friends, and adverts. The change has seen users’ engagement with Facebook pages drop precipitously, with publications reporting a 60% to 80% fall. If replicated more broadly, such a change would destroy many smaller publishers, as well as larger ones with an outsized reliance on social media referrals for visitors.

ASTRONOMY PICTURE OF THE DAY: Methuselah Nebula. Credit & Copyright: Don Goldman. The lovely, symmetric planetary nebula catalogued as MWP1 lies some 4,500 light-years away in the northern constellation Cygnus, the Swan. At 15 light-years, it is one of the largest planetary nebulae known. Based on its expansion rate the nebula has an age of 150 thousand years, a cosmic blink of an eye in the 10 billion year life of a sun-like star. But planetary nebulae represent a very brief final phase in stellar evolution, as the nebula’s central star shrugs off its outer layers to become a hot white dwarf. In fact, planetary nebulae ordinarily only last for 10 to 20 thousand years.

WORK OF ART: Studies of the Foetus in the Womb are two-coloured annotated sketches by Leonardo da Vinci made in around 1511. Da Vinci studied human embryology with the help of anatomist Marcantonio della Torre and saw the foetus within a cadaver. The studies were initially bequeathed to Francesco Melzi. In c. 1582–90 they were bought from his heirs by Pompeo Leoni, and by 1630 they belonged to Thomas Howard, 2nd Earl of Arundel. Since 1690 the studies have been housed in the Royal Collection, United Kingdom.
