That isn't to say you won't reach anyone new, but rather that the chances have decreased.
And the final thing I will say is that it's difficult to gain a reader following. I remember being a hundred chapters into my story and having 20 readers maybe with no comments, no reviews, barely any ratings, etc. It's really hard to gain a big following. And it's really easy to fall into a trap of looking at the big stories and thinking "Why don't I have as many followers as this!?"
It's because that story is one in a thousand, or even a million which was lucky enough to be displayed on the front page to everyone. And relying on luck like that is nothing more than deluding ones self.
