@Ray DesmerGetting any response from readers is, I suppose you could describe it as problematic.
Over the years I have tried eliciting response by including those who do, in stories as characters, to see if that would increase feedback by those readers noticing and who also wanted to get their names involved (turns out, not really). I also, the other year, put up a blog stating that if anyone responds, that I would kill them in a car crash in quite brutal ways. And I did, but the response before-hand wasn't that effective, just a few people responded (Or maybe they just didn't want to die!).
It may differ if you are one of the more 'popular' or 'mainstream' writers on here, but my lot (fans) aren't that bothered. I also considered the same idea you are suggesting, but the feedback wasn't that great and I shelved the idea, as it would only work if you had a decent response to the cliff hanger you (the writer) left, (I was thinking of a 'chose your own own story' type scenario at the time, with a poll of some description where the readers could chose out of a list of possible outcomes, and the one with the most votes was the route the story progressed.)
