I think most writers would agree though: any feedback, is better than none. :/ When one gets no replies, he would assume that the visit was too brief for a guest to even bother with one. I would rather get a negative critique, to better understand why such a lack of response, than to bash my head in wondering the next time I sit at the desk.
Writing is fun, but it's never fun to consistently produce stories just to find them each having the same lack of response, due to repeating the same mistakes. (Too long, not enough description, cheesy story-lines, lack of spell-checking, etc.)
