What experiences do you guys have in finding the right story length? Is less more? And / or does the reading public demand a shorter story?
I've found that readers are more, not less, likely to read a somewhat longer story than one of, say, only 1,000 - 1,500 words. I think, though, that Guy may be right that anything much over 5,000 words will receive diminished attention, which is why such stories are often divided into segments for posting.
When I write, I go until I've said what I've had to say. I think a tight shorter story of 1,000 +/~ words still can and should have some character development and plot, rather than merely a description of a spanking. I write many short stories that accomplish this, IMHO. There are certainly longer stories waiting to me told, some of which I've even tried my hand at.
I say - write what pleases you, rather than aiming for a particular length.
