Google docs is like an online word programme. You can save stories there, open them up, add more, edit, have it set up so you can see every different version of edits that you've done. I just find it so cool.

Right now I have two different stories open and I just go back to the one I'm feeling at that moment. Sometimes I'll only add a handful of words, other times thousands, but the pages are there waiting for when I have that urge.
