I've written quite a number of 'unfinished' stories. I post them onto story blogs and somehow I always manage to catch people's attention. I think the reason from thus is because I try to start well on grabbing their attention.
A secret I learnt some days ago is that nothing matter how bad your story is, once you have something of a mystery to begin with, people's attention will be caught. They'd want to know who killed the young lady? How the man discovered he was a werewolf, who raped here at six android why? The key is to reveal that there's a mystery to be solved. That's one thing in always do a it always works the trick.
