the troll has a point that external accountability fades, the audience thins and stops caring. so the honest use of a public journal is as training wheels: it can build the logging-everything habit while the novelty lasts, but the goal is to internalise the discipline so it survives after nobody is watching. if going public helps you build the habit, use it, just dont become dependent on the spectators, because they will leave and the discipline has to remain.
