I've been reading about Live Docs, which are not yet available on my site or my sandbox, and I've been struggling to find a good use case for them. I was concerned that there would be no history, but they do seem to retain some sort of version control, although I'm not clear how that works. Is it really the case that the only difference between Live Docs and Pages is that pages need the extra steps of Editing and Publishing, while Live Docs need the extra step of "Switch to Viewing" if you want to ensure you don't change content by accident? I'm really not sure what value this adds, so I'd love to hear from some folks who find them useful.
