Enlightened_Being People love quick updates, I’ve noticed this as well. Personally, I recommend making a choice between the following: quality or quantity.
This seems like an easy choice for most of us. After all; most writers strive to write quality stories. This, of course, takes time. And patience. Something readers often don’t have (the previous statement is a generalisation).
Novels with (several) daily updates are popular among readers due to the large quantity of reading material they are presented with. Yet often I find that this goes at the expense of the overall quality of the writing itself.
My point is that though it’s normal but upsetting to lose readers due to slower updates, it often translates in better work. And believe me, those who enjoy a good novel will stay and appreciate your work all the more.
Personally, I update once a week (or whenever I’m finally pleased with my writing). And I’m taking a two month long pause due to exams. This isn’t popular amongst general audiences, and I lose a lot of readers with it, but who am I to hold that against them.
So lastly, don’t mind those that leave. Know that those who stay will love you for the work and love you put in your writing.
