When you are editing in the dedicate edit page adding some awesomeness to a post and hit the "Save changes" button, you are warned if your edit will be writing over other awesome edit that happened while you were editing the post yourself. That lets you see what other people changed and merge their awesomeness with your own awesomeness, resulting in a much higher total combined awesomeness.
However, if you do the edits using the fancy inline editing feature (which, by the way, is awesome) your awesome changes will silently overwrite other users' also awesome changes, resulting in a post that is not as awesome as it could be. It can also make other people sad because their so carefully added awesomeness is now replaced by some other awesomeness added by a different user.
Would be nice if we could have the inline edits provide the same warning.
