Here's an interesting demo on Google docs: http://thenextweb.com/google/2012/06/22/this-is-the-coolest-demo-of-google-docs-youve-ever-seen/
I've always been a Word Girl, so I haven't explored Google docs much. I like the sharing aspect of Google docs, but I have no clue how to use it. And, there's something about privacy issues or copyright or something: what you write on Google docs becomes property of Google docs? I'll have to research that bit again.
So, any of you out there in Internet land, do you use Google docs? How? Why? When?
