I don't know anything about this site, except that a few writers I know say they have made $ posting their books in a serial fashion here: Radish Fiction.

Can you write serially? I have in the past, and it was fun, but I've gotten so skittish about deadlines these days. I think I'd have to have a story that "wrote itself" the way some blessedly do. Or I suppose write the whole book first, and then just release it chapter by chapter.
