I wasn't aware this sort of publishing opportunity was avalable, but it certainly bears looking into.
With Kindle Serials, Amazon hopes to reinvent a format that already exists. Jeff Bezosdragged out the obligatory Dickens reference at the LA press conference, but serial fiction had a presence online before Amazon (and a presence offline after Dickens: Armistead Maupin’s “Tales of the City” and Candace Bushnell’s “Sex and the City,” for instance). The website Tuesday Serial compiles links to many online serials and offers advice about writing them. Authors likeClaudia Christian and Lyn Thorne-Alder have written online serials for years. And longform journalism site and e-singles publisher Byliner launched Byliner Serials last month.
