There is a problem with content on the internet. It is produced only to be discarded. Information deserves more respect than this. You put the work into writing a meaningful piece of text. The text needs occasional updates to stay correct or relevant, and that is where Redraftable comes in.
Wikis take steps to avoid staleness through crude version control. Old information is hid away in the 'history', and community interaction is hid away in 'talk'. Trying to sort out the story behind a page's development is a painful process.
Watching change should not be painful, it should be enlightening. Neither blogs nor wikis allow for the description of a journey, where every step presents new options to explore.
Remember your English writing classes? You would write double spaced drafts, sharing them with your friends. They would fill the margins with revisions and suggestions. Draft after draft, the paper would evolve under the pressure and forces of of one's peers and instructors. This sort of tightly coupled interaction humanizes writers and readers. Writers and commentary both should be highly visible and explorable.
Have you ever used archive.org as an archeological tool? Go find some website you like, punch it in and see how it mutated over the past several years. There is something profound about seeing an idea grow and mature. I want this experience seamlessly built in to everything I do.
I want to spend my time doing awesome things, not drinking a firehose of other people's RSS. I want to find what someone actually thinks about a topic, not their most popular blog post. I want to be handed a diagram of how their opinions evolved, not tease it out from pages of unrelated garbage.
These ideas make up the founding princples of Redraftable. Chronological exploration should be slick and easy. Discourse should be tightly coupled to the text it comments on, as well as the revision it inspires. It's not a blog or wiki. It is meant for writers, hackers and makers. It is for anyone who wishes to preserve the journey of their accomplishments. Think of Redraftable as a book, where each chapter is a different project. Every revision is at your fingertips, and comments are in the margins.
