I've had a novel going since December, and it's at 244k words at this point and the only comment on the entire thing is my own warning there's a sex scene next chapter and that you can skip over it if you want.
I'm not planning on stopping any time soon, but it's really disparaging to not get any kind of feedback at all. Maybe I'm just doing a horrible job at promoting it, maybe it's just bad and no one wants to read it, but if it's the former, I at least want to be told that so I know what to fix.
I guess I just want to know how many subscribers people have gotten before they start expecting feedback every now and then so that I know what to expect.
