Membership history

Growth

293 measurements spanning 11 days, net +32,190. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 268,708–310,555 and does not start at zero.
