Yeah... What Zake said. As far as I'm concerned, it's already easy to create the games, it's already easy to go back and forth between chapters. Inventory, skills, attributes and randomness are all pretty simple and we can already share stories in a quick and efficient manner. As for lots of people being able to read them, this is the internet. Everybody with internet connection can read them. That's enough for me. 
Sorry, but I'm just really, really unsure what you're planning on doing that's an improvement to what we already have.
