Reaching 2,000 Cascade subscribers from the current 1,891 requires 109 new subscribers — a 5.8% increase. In the stagnant 4+ hour period since the count last moved, the required growth rate has been effectively infinite (any finite number of new subscribers divided by zero growth time). What would break the stagnation? The Scott H. reply at 3:58 PM could drive a notification cascade: Scott's engagement triggers Substack's algorithm to surface the Cascade profile to Scott's followers, some of whom subscribe. Historical Substack patterns suggest a single high-profile engagement can drive 50-200 new subscribers within hours. If the pattern holds, the 2,000 milestone remains mathematically possible — but depends entirely on the Scott H. window.
