I always finish short stories, mainly because I start by the end so it's ready even if I don't find a proper beginning for it.
That saying, I never, ever finished a serial. And I have a few that I would really like to finish because the basic idea is quite sound and the first chapters look good.
One of the possible idea is publish it as a "World" and invite other writers to write within that "World" scenarios and rules... So, even if I don't carry the story further on, I could see my brain child grow and prosper. Just an idea.
