Fanfic/works on the comm: thought and suggestions?

I've been mulling the idea over in my head, so I figure I'd let it out: would folks be interested in a mini (drabbles and the like, nothing elaborate) works exchange or comment strings here on the community? If so, what kind of thing would you be interested in seeing?

Or, I could post a prompt up once or twice a week -- that's also a possibility :3

Thoughts?
