TechCrunch: Amazon has a new crowd-publishing platform called Write On, which appears to be a direct competitor to Wattpad, the social network with self-publishing authors offering up their content for free and feedback. The Amazon version launched last October as an invite-only beta, but now is a full-fledged product available to all. The Amazon platform allows anyone to share anything they’re working on at any stage. They can offer full works, chapters, outlines, vague character sketches or even just single snippets and poll the community for feedback.
