GeekinKorea, Megalodon has a built in notification service. Whenever I get a reply, follower, reply, message, etc, I see it immediately.
My posting habits and frequency greatly increased immediately after enabling this feature compared to Fedilab where those notifications are turned off.
I am more engaged with Mastodon when I get notifications often.
Tweak what notifications you want to receive, or turn them off completely! That rush of dopamine changes behaviors!
