That's why there is a phrase: "Keep Writing Even if Nobody Reads."
I mean, instead of focusing on "why no one gives us engagement", why don't they focus on their IF... Pretty sure if they release new chapters steadily, they will get engagement boost again...
If they create something just for engagement, now I know why they are slow at updating their IF...
The update is also sometimes so slow, making others lose interest too... In my view, I also got tired if I interacting with IF who rarely update...
