I want to come down very, very strongly on the original poster's side.

Unfinished stories are very frustrating. I've even thought of a little 'check' sign to mark those with an actual ending (however open or scrambled) in my private catalogue. But I realize that would be unfair.

Of course writers do it as a hobby. And all kinds of accidents can interrupt their hobby. But in many cases what we have is the literary equivalent of the guy who shoots his wad, turns over and snores. The writer gets to a climax of sorts, then grows completely bored with the story, if not downright hostile. It happens all the time, mainly with male writers!

I understand the lack of feedback is much to blame. Much of my collection comes from outside BDSM Library. Whenever I came upon a hot text with no ending, I spent quite a lot of effort tracking down the author, and doing a lot of indecent coaxing and ego massaging (when I felt it was deserved). Guess what, it worked - sometimes. Somehow this site's review/vote format repels me a bit - maybe if I can bring myself to think of it as a slave's duty...

For the one and only book I wrote, I did not start writing before having a synopsis, character files and background data pat. The reward is then that you can write in any old order, like movies are actually shot. This removes much of the drudgery of going from one scene to the other. But the creative process is different in each of us so there's no rule - except that the prevalence of unfinished stories does not make them any more acceptable. (sorry guys, that book is in French)

This does not make me any less grateful to the writers who grace us with their wicked creations! And even 'endless' stories can be delicious, skill helping...
