Social media has made the Goffmanian insight — that all social life is performance — impossible to ignore, by providing a stage with an audience, analytics, and the intoxicating feedback of engagement. The question is not whether online identity is real (it is) but whether the optimization it demands — for likability, legibility, and reach — is pulling the performed self away from the interior one. The person who can no longer remember what they actually think, before the consideration of how it will land, is in Juana's terms the person who has put on the mask so long they have forgotten their own face.
Each step builds on the last.
