My vote is for Post. Because even if I don't have any real follow up chapters YET...It may inspire others to contribute.
Well, I guess I won't then. Even if it means it's going to be another few weeks or months before I get around to some meaty chapters.
If you really want someone else to work on it, pick a few people who you can trust and make them editors.
It's less that I really want someone else to work on it and more that I'm not sure exactly when I'm going to get around to writing more for it.
I could take a look at the story if you like, give you a few pointers/suggestions/hopeful-sources-of-inspiration: perhaps?
