I try to keep up with my lemmy inbox throughout the day, but I post a lot and it really piles up. Side note- I’ve noticed an uptick in comment activity lately too. The last couple of mornings, I’ve woken up to 100+ messages. That used to be maybe 35-40.
FWIW the number of Active Users on Lemmy + KBin has levelled off recently: https://fedidb.org/current-events/threadiverse (i.e. maybe we’ve stopped losing users from the summer influx? Or maybe lurkers are now commenting more?)
