Publisher's Weekly has a great story on a new digital publishing company that is launching today: Coliloquy. (Note: I recently sold a client's romance to them, so my incredibly positive view of them is biased.)
PW said: Coliloquy, a Palo Alto-based startup launching today exclusively on Amazon Kindle E-Ink devices, has a new take on digital publishing. Explained simply, it’s an e-book-age version on choose-your-own-adventure, allowing readers to make choices within a book that affect its outcome; in some cases, with continuing serial novels, those choices can actually be sent back to the writer to consider as he or she is writing the next chapters of the book."
