Grieving used to be a public affair, but it was gradually suppressed in the 20th century as psychology made those outward displays socially unacceptable. Death and loss were things you were supposed to deal with privately. Well, public mourning is back -- and you largely have the internet to thank for it. As The Atlantic notes, the deaths of David Bowie and other famous artists in recent months (including Alan Rickman, Glenn Frey and Scott Weiland) have shown that social networks are quickly becoming mainstays of the grieving process. Those profile pages, mentions and hashtags enable a sort of connected wake, a place where everyone can share their fond memories with fellow sympathizers.
