blimp:
I would agree with you Danny, it should be entirely voluntary. The last thing a writer wants is people commenting only because they feel obliged to.
What blithering nonsense. Any reader who doesn't comment should be drawn and quartered, and booted from the site, more or less in that order. What are they thinking in their deafening, non-commenting silence? That this place is some kind of bloody library (I mean, before the drawing and quartering part anyway).
Now don't go thinking I'm one of those comment-obsessed authors. I bet I don't think about comments more than once a day (that one time being approximately from 6:30 am to 11:30 pm). And I've only ever written one story about readers who fail to comment and what might happen to them. It happens to be a very good story, but none-the-less it's singular (in every sense of the word).
