<Snipped quote>	What about users who occasionally leave a page open for three days and expect it to still be there through browser restarts and what not?

From what Mahz described, it would appear that if you are on the page with your half-completed post in it, then it would keep refreshing the draft, pushing back the expiry deadline (unless the editor has to be in focus. Then you might have some issues).

Of course, leaving a page open for three days and counting on nothing going wrong is asking for trouble. If I leave a post half-done for any length of time I save it as a text file on my computer, so it will be safe. If you've got your own system for that (which you suggest that you do), then that should do. Conversely, Mahz's system is a system for protection from data loss, from brief closures of the browser or site or internet connection, not a system for long-term draft storage.
