thats exactly what I was thinking and wondering if already mentioned book in my post made maybe 1% or 10% of readers stop buying unfinished books. that sould hurt other authors would not it? but thing I am really interested if such a people are so few that it wont affect other authors, or is there high amount that other authors would feel it.

you get less income, you think less people carw about your book and your motivation drops. just because people are scared of starting new book since they forget first book before 2nd is released. or they are scared that they will get unfinished book. and they dont dare to read your book. otherwise author would have more readers
