If you haven't noticed how many changes have been happening in the world of publishing, well you've either taken a really, really long nap or you just don't care. For those of us who do care, the changes have been monumental and eye-opening. Most of the changes revolve around the proliferation of e-readers and e-books. NOTE: You don't have to have an e-reader to read an e-book but many of us do.
So, what's a writer to do! EMBRACE IT!!!!
Charles Dickens was known during his day for serializing his stories/novels. (http://en.wikipedia.org/wiki/Charles_Dickens), many of which dealt with social reform issues. I can easily see a return to serialized novels with the e-book format. In fact, many publishers have seen a spike in sales of novellas and short stories with e-books.
So, instead of becoming a serial killer, become a serial novelist.
