Had a busy day so I'm not sure if this has made the rounds here yet BUT: #PapuaNewGuinea has shut down #Facebook for a month to research what facebook is doing with and to its users, how it influences them and their health: http://news.pngfacts.com/2018/05/papua-new-guinea-to-shutdown-facebook.html
Sounds almost healthy until you get to the point where it's actually about #censorship an how to better control, or uh, "curate" the experience
