Write a short story, make it seem interesting and slightly confusing, and then end it with a twist ending that makes little sense (bonus points if its in first person!). Then people will start posting just to ask what it all means or what really happened. Did it with my own short story, "Paranoia," (link in one of my content blocks) and it got the most replies of any of my short stories ever because of it.

I've only ever tried this with short stories, as I doubt it would work as effectively in epics or comedies, though it possibly could if you are a good enough writer, I don't know.

True, it may seem a little unorthodox or whatever the word you may use to describe it and I don't recommend doing it for every story you write unless that is your style. But it works if you want replies and don't care what they say. Whether you wish to do it is up to you, however.
