We all know that the vast majority of our readers aren't going to leave comments, no matter what site we're on. They're happy to just read the story and come back when more chapters get posted. So let's say that one of my chapters has two hundred readers. Two of those readers left comments saying they don't like the way the story is going. Those two comments are the only tangible feedback you've gotten for that chapter. But if two people left negative comments, does that mean that 198 people liked the story enough that they didn't feel the need to leave a comment criticizing it?
What do you guys think is more indicative of how you should proceed? Silent acceptance of where a story is going, or vocal criticism for what someone doesn't like?
That depends entirely on the story, and your intent. (If you're writing a choose-your-own-adventure style series, you may want to consider the feedback as a means of promoting additional engagement with the readers).
No work of fiction or art will be universally appealing, so there are sure to be folks who will love it, and folks who will hate it. No matter what you do.
So as for what is most indicative of how you should proceed, that's simple.
Write the story you want to write, for the audience you want to write for.
There will always be that vocal minority, and they can be safely ignored for the most part.
As for re-writing, that would really depend on how you view the work itself.
If re-writing would both drastically improve the quality overall, or sharpen the story to better match your vision, by all means do it.
Otherwise, don't. The only real changes that you might want to consider making would be spelling, or grammatical, ones if they are necessary.
I hope this helps.
