The ability to edit your page at any time from anywhere is key! I dislike how they have made it so that if you click "edit" in another tab/window than where you are currently editing (like when you're not logged into our website) then all of my changes will be lost and reverted back to what was originally there before i clicked "Edit".
If this behavior can't change maybe consider using something else like Instapaper for reading articles while offline? Just make sure you keep up with everything as soon as possible after publishing because once its published its pretty much gone until someone reads or clicks through to get more information about whatever link we've posted. This saves us tons of money by allowing us to test out different titles, images etc without having to wait months between testing things vs. doing them live which would cost even MORE.
