Draft is a way for writers to collaborate online writing in Markdown with version control. It’s very straightforward so far, which is probably a good way to roll. Export doesn’t seem to be working for me at the moment, but the plan appears to be to export to Dropbox et al and keep things in sync. That would be nice. It’s great to see these kinds of simple text-editor collaborative services starting to spring up outside of the Word/Google Doc ecosystem. It’ll be interesting to see how Draft compares to Editorially, which I am hugely looking forward to.
