You are right about not getting any comments here. I am new and posted a couple of chapters. On the second posting I asked readers to follow and comment. I got a LIKE and two followers, I got no comments. The numbers show a few hundred readers, but nobody said, nice story, liked it, nothing.
I found another site, Nifty, and posted a story there, immediately I got emails from readers. What a huge difference! I stopped posting here, just look in from time to time to see if anything's happening, but nothing is.
I can't really see myself posting chapters into a void. I agree with you, that if like 200 or 300 people read a chapter, then a few comments to the guy who wrote it, isn't too much to expect. If the readers out there can't be bothered to just say, liked it, I can't be bothered to post it.
