L. M. Sacasas’s essay on social media, The Inescapable Town Square:
Under these conditions, the function of externalized memory shifts. It is no longer for recording the past or preserving knowledge, but now for acting in the present. Memory loses its context and story. It neither integrates a society, as the rituals of collective remembering in oral societies did, nor does it sustain an individual’s experience of the self, as writing did in the age of print. Memory, much of it highly personal, is “there,” but without the person necessarily remembering. This allows memory to become weaponized. It exists in massive and accessible databases, ready to be resurfaced, without context and without warning, in a newly contentious field of public discourse.
