My sister was asking me for articles on how social media companies manipulate their users to spend more and more time on them. Things like "infinite scrolling" and Snaps "streaks" feature.<p>I seem to remember an x-google employee? putting out a manifesto suggesting that we should display a timer showing how long you've spent etc. I can't find the link now.<p>Anyway, if you do have any decent articles on the tricks and risks of using social media, particularly regarding children please pass them on.
