Etherpad
Etherpad allows you to edit documents collaboratively in real-time, much like a live multi-player editor that runs in your browser. Write articles, press releases, to-do lists, etc. together with your friends, fellow students or colleagues, all working on the same document at the same time. All instances provide access to all data through a well-documented API and support import/export to many major data exchange formats. And if the built-in feature set isn't enough for you, there's tons of plugins that allow you to customize your instance to suit your needs. You don't need to set up a server and install Etherpad in order to use it. Just pick one of the publicly available instances that friendly people from everywhere around the world have set up. Etherpad is an open source project.

Draft
You don't need writing software; you need someone's feedback on your writing. You don't need version control software; you need to find all the things you've written without fear. You don't need distraction free text editors; you need to find ways to write more concisely, more clearly. You don't need real time collaboration software; you need a bigger audience for your writing. We're working on Draft to provide what you need. When I share a Google Doc, collaborators overwrite my master copy. It's insanely difficult to accept individual changes they've made. However, when you share your document using Draft, any changes your collaborator makes are on their own copy of the document, and you get to accept or ignore each individual change they make. With Draft, as you go along, you can mark major versions of your work. When you want to compare your old drafts, you have a powerful view to see how your document changed over time.
